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]

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 27, 2024 | The c.382G>C (p.G128R) alteration is located in exon 1 (coding exon 1) of the WDR81 gene. This alteration results from a G to C substitution at nucleotide position 382, causing the glycine (G) at amino acid position 128 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
