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]

Collection Method: clinical testing

The c.530G>A (p.R177Q) alteration is located in exon 5 (coding exon 5) of the SASH3 gene. This alteration results from a G to A substitution at nucleotide position 530, causing the arginine (R) at amino acid position 177 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
