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]

SASH3 Gene-Disease associations (from GenCC):

• immunodeficiency 102

  Inheritance: XL Classification: DEFINITIVE, STRONG Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics

Collection Method: clinical testing

The c.547G>A (p.D183N) 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 547, causing the aspartic acid (D) at amino acid position 183 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
