Genes affected

WDR49 (HGNC:26587): (WD repeat domain 49) This gene encodes a member of the WD repeat protein family with nine WD repeats. 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. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2017]

The c.1353G>T (p.E451D) alteration is located in exon 11 (coding exon 10) of the WDR49 gene. This alteration results from a G to T substitution at nucleotide position 1353, causing the glutamic acid (E) at amino acid position 451 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
