Variant 13-26665117-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 1P and 4B. PP3BS2

The ENST00000335327.6(WASF3):c.223C>T(p.Arg75Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000753 in 1,461,790 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R75L) has been classified as Uncertain significance.

Genes affected

WASF3 (HGNC:12734): (WASP family member 3) This gene encodes a member of the Wiskott-Aldrich syndrome protein family. The gene product is a protein that forms a multiprotein complex that links receptor kinases and actin. Binding to actin occurs through a C-terminal verprolin homology domain in all family members. The multiprotein complex serves to tranduce signals that involve changes in cell shape, motility or function. A pseudogene of this gene have been defined on chromosome 6. Alternative splicing results in multiple transcript variants [provided by RefSeq, May 2014]

The c.223C>T (p.R75C) alteration is located in exon 1 (coding exon 1) of the WASF3 gene. This alteration results from a C to T substitution at nucleotide position 223, causing the arginine (R) at amino acid position 75 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
