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.

The c.118A>G (p.I40V) 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 118, causing the isoleucine (I) at amino acid position 40 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Microcephaly 2, primary, autosomal recessive, with or without cortical malformations

Benign:1
