Summary
Researchers identified a new L1CAM gene mutation causing X-linked hydrocephalus (XLH). This finding confirms L1CAM
Area of Science:
- Genetics
- Neuroscience
Background:
- X-linked hydrocephalus (XLH) is a genetic disorder often linked to the L1CAM gene.
- The L1 cell adhesion molecule (L1CAM) protein is vital for nervous system development.
Observation:
- A novel mutation, c.2491delG (p.V831fs), was identified in the L1CAM gene of a hydrocephalic fetus.
- This mutation occurred in exon 19 of L1CAM and was analyzed using whole-exome sequencing.
Findings:
- The identified L1CAM variant causes a frameshift mutation, potentially disrupting L1CAM protein function.
- This novel mutation is disease-causing and contributes to X-linked hydrocephalus.
Implications:
- This study confirms L1CAM as a key gene in XLH pathogenesis.
- Further understanding of L1CAM mutations can aid in diagnosing and potentially treating hydrocephalus.

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

01:19X-linked Traits
58.1K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...
