Genes affected

SSX2IP (HGNC:16509): (SSX family member 2 interacting protein) This gene encodes a protein that binds the cancer-testis antigen Synovial Sarcoma X breakpoint 2 protein. The encoded protein may regulate the activity of Synovial Sarcoma X breakpoint 2 protein in malignant cells. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 3. [provided by RefSeq, Oct 2009]

Ambry Genetics

Jun 05, 2023

The c.1649G>A (p.R550H) alteration is located in exon 14 (coding exon 12) of the SSX2IP gene. This alteration results from a G to A substitution at nucleotide position 1649, causing the arginine (R) at amino acid position 550 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
