Genes affected

SHISA3 (HGNC:25159): (shisa family member 3) This gene encodes a single-transmembrane protein which is one of nine members of a family of transmembrane adaptors that modulate both WNT and FGF signaling by blocking the maturation and transport of their receptors to the cell surface. Members of this family contain an N-terminal cysteine-rich domain with a distinct cysteine pattern, a single transmembrane domain, and a C-terminal proline-rich, low complexity region. The encoded protein acts as a tumor suppressor by accelerating beta-catenin degradation. [provided by RefSeq, Jul 2017]

Collection Method: clinical testing

The c.600C>A (p.H200Q) alteration is located in exon 2 (coding exon 2) of the SHISA3 gene. This alteration results from a C to A substitution at nucleotide position 600, causing the histidine (H) at amino acid position 200 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
