Abstract:
Dandy-Walker malformation (DWM) is often sporadic, but there are a growing number of genetic disorders that have been associated with this condition. We present a female individual with a de novo variant in ABL1, c.734A>G (p.Y245), who was diagnosed prenatally with DWM. ABL1-related neurodevelopmental disorder was recently identified but brain malformations have not been well characterized to date. We reviewed the published literature and identified one additional individual with DWM and ABL1-related disorder, which suggests a possible association with this malformation.

Lethal Alleles
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...

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
