Genes affected

TSSK1B (HGNC:14968): (testis specific serine kinase 1B) TSSK1 belongs to a family of serine/threonine kinases highly expressed in testis (Hao et al., 2004 [PubMed 15044604]).[supplied by OMIM, Mar 2008]

TSSK1B links:

MCC (HGNC:6935): (MCC regulator of WNT signaling pathway) This gene is a candidate colorectal tumor suppressor gene that is thought to negatively regulate cell cycle progression. The orthologous gene in the mouse expresses a phosphoprotein associated with the plasma membrane and membrane organelles, and overexpression of the mouse protein inhibits entry into S phase. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

May 11, 2022

The c.500G>A (p.G167D) alteration is located in exon 1 (coding exon 1) of the TSSK1B gene. This alteration results from a G to A substitution at nucleotide position 500, causing the glycine (G) at amino acid position 167 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
