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.

WDR62 Gene-Disease associations (from GenCC):
  • microcephaly 2, primary, autosomal recessive, with or without cortical malformations

The c.2729T>A (p.L910Q) alteration is located in exon 22 (coding exon 22) of the WDR62 gene. This alteration results from a T to A substitution at nucleotide position 2729, causing the leucine (L) at amino acid position 910 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces leucine, which is neutral and non-polar, with glutamine, which is neutral and polar, at codon 910 of the WDR62 protein (p.Leu910Gln). ClinVar contains an entry for this variant (Variation ID: 437290). This variant has not been reported in the literature in individuals affected with WDR62-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.006%). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). -
