Genetic Variant WWC1:c.2280+45_2280+60delGCTGGCTGGCTGGCTG (chr5-168431457-TCTGGCTGGCTGGCTGG-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_015238.3(WWC1):c.2280+45_2280+60delGCTGGCTGGCTGGCTG variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000322 in 1,414,482 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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]
