A genetic disorder is an illness caused by one or more abnormalities in the genome, especially a

condition that is present from birth (congenital). Most genetic disorders are quite rare and affect one

person in every several thousands or millions.

Genetic disorders are heritable, and are passed down from the parents' genes. Other defects may be

caused by new mutations or changes to the DNA. In such cases, the defect will only be heritable if it

occurs in the germ line. The same disease, such as some forms of cancer, may be caused by an

inherited genetic condition in some people, by new mutations in other people, and by nongenetic causes

in still other people.

Some types of recessive gene disorders confer an advantage in certain environments when only one

copy of the gene is present.[1]

X-linked

A single gene disorder is the

result of a single mutated gene.

Over 4000 human diseases are

caused by single gene defects.

Single gene disorders can be

passed on to subsequent

generations in several

ways. Genomic

imprinting anduniparental disomy, however, may affect inheritance patterns. The divisions

between recessive and dominant types are not "hard and fast", although the divisions

between autosomal and X-linked types are (since the latter types are distinguished purely based on the

chromosomal location of the gene). For example, achondroplasia is typically considered a dominant

disorder, but children with two genes for achondroplasia have a severe skeletal disorder of which

achondroplasics could be viewed as carriers. Sickle-cell anemia is also considered a recessive condition,

but heterozygous carriers have increased resistance to malaria in early childhood, which could be

described as a related dominant condition.[4]

When a couple where one partner or both are sufferers or

carriers of a single gene disorder and wish to have a child, they can do so through in vitro fertilization,

which means they can then have a preimplantation genetic diagnosis to check whether the embryo has

the genetic disorder.[5]

Autosomal dominant[

Only one mutated copy of the gene will be necessary for a person to be affected by an autosomal

dominant disorder. Each affected person usually has one affected parent.[6]

The chance a child will inherit

the mutated gene is 50%. Autosomal dominant conditions sometimes have reduced penetrance, which

means although only one mutated copy is needed, not all individuals who inherit that mutation go on to

develop the disease. Examples of this type of disorder are Huntington's disease,[7]

neurofibromatosis type

1, neurofibromatosis type 2, Marfan syndrome, hereditary nonpolyposis colorectal cancer, and hereditary

multiple exostoses, which is a highly penetrant autosomal dominant disorder. Birth defects are also called

congenital anomalies.

Autosomal recessive

Two copies of the gene must be mutated for a person to be affected by an autosomal recessive disorder.

An affected person usually has unaffected parents who each carry a single copy of the mutated gene

(and are referred to as carriers). Two unaffected people who each carry one copy of the mutated gene

have a 25% chance with each pregnancy of having a child affected by the disorder. Examples of this type

of disorder are Medium-chain acyl-CoA dehydrogenase deficiency, cystic fibrosis, sickle-cell

disease, Tay-Sachs disease, Niemann-Pick disease, spinal muscular atrophy, and Roberts syndrome.

Certain other phenotypes, such as wet versus dry earwax, are also determined in an autosomal recessive

fashion.[8][9]

X-linked dominant

X-linked dominant disorders are caused by mutations in genes on the X chromosome. Only a few

disorders have this inheritance pattern, with a prime example being X-linked hypophosphatemic rickets.

Males and females are both affected in these disorders, with males typically being more severely affected

Duchenne muscular dystrophy 1 in 7,000

Hemophilia 1 in 10,000

Values are for liveborn infants

than females. Some X-linked dominant conditions, such as Rett syndrome, incontinentia pigmenti type 2

and Aicardi syndrome, are usually fatal in males either in utero or shortly after birth, and are therefore

predominantly seen in females. Exceptions to this finding are extremely rare cases in which boys

with Klinefelter syndrome (47,XXY) also inherit an X-linked dominant condition and exhibit symptoms

more similar to those of a female in terms of disease severity. The chance of passing on an X-linked

dominant disorder differs between men and women. The sons of a man with an X-linked dominant

disorder will all be unaffected (since they receive their father's Y chromosome), and his daughters will all

inherit the condition. A woman with an X-linked dominant disorder has a 50% chance of having an

affected fetus with each pregnancy, although it should be noted that in cases such as incontinentia

pigmenti, only female offspring are generally viable. In addition, although these conditions do not alter

fertility per se, individuals with Rett syndrome or Aicardi syndrome rarely reproduce.[citation needed]

X-linked recessive

X-linked recessive conditions are also caused by mutations in genes on the X chromosome. Males are

more frequently affected than females, and the chance of passing on the disorder differs between men

and women. The sons of a man with an X-linked recessive disorder will not be affected, and his

daughters will carry one copy of the mutated gene. A woman who is a carrier of an X-linked recessive

disorder (XRX

r) has a 50% chance of having sons who are affected and a 50% chance of having

daughters who carry one copy of the mutated gene and are therefore carriers. X-linked recessive

conditions include the serious diseases hemophilia A, Duchenne muscular dystrophy, and Lesch-Nyhan

syndrome, as well as common and less serious conditions such as male pattern baldness and red-

green color blindness. X-linked recessive conditions can sometimes manifest in females due to skewed

X-inactivation or monosomy X (Turner syndrome).

Y-linked

Y-linked disorders are caused by mutations on the Y chromosome. Because males inherit a Y

chromosome from their fathers, every son of an affected father will be affected. Because females only

inherit an X chromosome from their fathers, and never a Y chromosome, female offspring of affected

fathers are never affected.

Since the Y chromosome is relatively small and contains very few genes, relatively few Y-linked disorders

occur.[citation needed]

Often, the symptoms include infertility, which may be circumvented with the help of

some fertility treatments. Examples are male infertility.[citation needed]

Mitochondrial

This type of inheritance, also known as maternal inheritance, applies to genes in mitochondrial DNA.

Because only egg cells contribute mitochondria to the developing embryo, only mothers can pass on

mitochondrial conditions to their children. An example of this type of disorder is Leber's hereditary optic

neuropathy.

Multifactorial and polygenic (complex) disorders

Genetic disorders may also be complex, multifactorial, or polygenic, meaning they are likely associated

with the effects of multiple genes in combination with lifestyles and environmental factors. Multifactorial

disorders include heart disease and diabetes. Although complex disorders often cluster in families, they

do not have a clear-cut pattern of inheritance. This makes it difficult to determine a person’s risk of

inheriting or passing on these disorders. Complex disorders are also difficult to study and treat because

the specific factors that cause most of these disorders have not yet been identified.

On a pedigree, polygenic diseases do tend to "run in families", but the inheritance does not fit simple

patterns as with Mendelian diseases. But this does not mean that the genes cannot eventually be located

and studied. There is also a strong environmental component to many of them (e.g., blood pressure).

Chromosome Map

Our genetic information is stored in 23 pairs of chromosomes that vary widely in size and shape.

Chromosome 1 is the largest and is over three times bigger than chromosome 22. The 23rd pair of

chromosomes are two special chromosomes, X and Y, that determine our sex. Females have a pair of X

chromosomes (46, XX), whereas males have one X and one Y chromosomes (46, XY). Chromosomes

are made of DNA, and genes are special units of chromosomal DNA. Each chromosome is a very long

molecule, so it needs to be wrapped tightly around proteins for efficient packaging.

Near the center of each chromosome is its centromere, a narrow region that divides the chromosome into

a long arm (q) and a short arm (p). We can further divide the chromosomes using special stains that

produce stripes known as a banding pattern. Each chromosome has a distinct banding pattern, and each

band is numbered to help identify a particular region of a chromosome. This method of mapping a gene to

a particular band of the chromosome is called cytogenetic mapping. For example, the hemoglobin beta

gene (HBB) is found on chromosome 11p15.4. This means that the HBB gene lies on the short arm (p) of

chromosome 11 and is found at the band labeled 15.4.

With the advent of new techniques in DNA analysis, we are able to look at the chromosome in much

greater detail. Whereas cytogenetic mapping gives a bird's eye view of the chromosome, more modern

methods show DNA at a much higher resolution. The Human Genome Project aims to identify and

sequence the ~30,000 genes in human DNA.

Kenta Nakai and Hiroshi Sakamoto Construction of a novel database containing aberrant splicing mutations of

mammalian genes. Gene 141: 171-7 (1994)

Compilation of aberrant splicing phenomena.

# of EX represents the total number of exons in each gene. SS indicates the 5' or 3' splice site

affected by mutations. IVS represents the position number of mutated introns. When mutations

were observed within exon sequences, the nearest introns are noted. Change indicates

description of each mutation, for example, G1T indicates that the original nucleotide G at

position +1 was changed for A; ins[+2T] indicates that the nucleotide T was inserted at position

+2; del[-29:+1] indicates that nucleotides at positions from -29 to +1 were deleted; TTT-17:-

15AAA indicates that the sequence TTT at positions from -17 to -15 was changed for the

sequence AAA. Result(major) andResult(minor) indicate the resultant aberrant splicing

pattern, for example, ES[8] indicates that the eighth exon was skipped; IR[7] indicates that the

seventh intron was retained; C5[+88] indicates that a cryptic 5' splice site was activated at

position +88; N3[-17] indicates that a new 3' splice site was activated at position -17. In some

cases, comments are added, for example, EXP indicates that the result was not derived from

direct analysis of the cDNA sequence. A typical case is that a portion of the mutated gene was

analyzed using transfection into cultured cells. Similarly, induced indicates that an aberrant

splicing was induced by artificial mutagenesis. Ref. indicates the reference number.
