Genes affected

WDR62 (HGNC:24502): (WD repeat domain 62) This gene is proposed to play a role in cerebral cortical development. Mutations in this gene have been associated with microencephaly, cortical malformations, and cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2011]

Collection Method:clinical testing

The c.85A>G (p.R29G) alteration is located in exon 1 (coding exon 1) of the WDR62 gene. This alteration results from a A to G substitution at nucleotide position 85, causing the arginine (R) at amino acid position 29 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
