Genes affected

WDR81 (HGNC:26600): (WD repeat domain 81) This gene encodes a multi-domain transmembrane protein which is predominantly expressed in the brain and is thought to play a role in endolysosomal trafficking. Mutations in this gene are associated with an autosomal recessive form of a syndrome exhibiting cerebellar ataxia, cognitive disability, and disequilibrium (CAMRQ2). Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2017]

The c.151G>A (p.G51S) alteration is located in exon 1 (coding exon 1) of the WDR81 gene. This alteration results from a G to A substitution at nucleotide position 151, causing the glycine (G) at amino acid position 51 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
