Dandy-Walker malformation in an individual with ABL1 variant.

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.
