Genes affected
WDR6 (HGNC:12758): (WD repeat domain 6) This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. The encoded protein interacts with serine/threonine kinase 11, and is implicated in cell growth arrest. Alternative splicing results in multiple transcript variants encoding different isoforms.

The c.1105G>A (p.A369T) alteration is located in exon 2 (coding exon 2) of the WDR6 gene. This alteration results from a G to A substitution at nucleotide position 1105, causing the alanine (A) at amino acid position 369 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
