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]

The c.596G>A (p.S199N) alteration is located in exon 2 (coding exon 2) of the SHISA3 gene. This alteration results from a G to A substitution at nucleotide position 596, causing the serine (S) at amino acid position 199 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
