Genes affected

SASH3 (HGNC:15975): (SAM and SH3 domain containing 3) The protein encoded by this gene contains a Src homology-3 (SH3) domain and a sterile alpha motif (SAM), both of which are found in proteins involved in cell signaling. This protein may function as a signaling adapter protein in lymphocytes.[provided by RefSeq, Sep 2009]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.595G>A (p.G199R) alteration is located in exon 6 (coding exon 6) of the SASH3 gene. This alteration results from a G to A substitution at nucleotide position 595, causing the glycine (G) at amino acid position 199 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
