Genes affected

WWC1 (HGNC:29435): (WW and C2 domain containing 1) The protein encoded by this gene is a cytoplasmic phosphoprotein that interacts with PRKC-zeta and dynein light chain-1. Alleles of this gene have been found that enhance memory in some individuals. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010]

The c.102G>T (p.W34C) alteration is located in exon 1 (coding exon 1) of the WWC1 gene. This alteration results from a G to T substitution at nucleotide position 102, causing the tryptophan (W) at amino acid position 34 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
