Genes affected

STYXL2 (HGNC:25034): (serine/threonine/tyrosine interacting like 2) Predicted to enable protein tyrosine/serine/threonine phosphatase activity. Predicted to be involved in protein dephosphorylation. Predicted to be located in sarcomere. [provided by Alliance of Genome Resources, Apr 2022]

STYXL2 links:

GPA33 (HGNC:4445): (glycoprotein A33) The glycoprotein encoded by this gene is a cell surface antigen that is expressed in greater than 95% of human colon cancers. The open reading frame encodes a 319-amino acid polypeptide having a putative secretory signal sequence and 3 potential glycosylation sites. The predicted mature protein has a 213-amino acid extracellular region, a single transmembrane domain, and a 62-amino acid intracellular tail. The sequence of the extracellular region contains 2 domains characteristic of the CD2 subgroup of the immunoglobulin (Ig) superfamily. [provided by RefSeq, Jul 2008]

The c.63C>A (p.N21K) alteration is located in exon 1 (coding exon 1) of the DUSP27 gene. This alteration results from a C to A substitution at nucleotide position 63, causing the asparagine (N) at amino acid position 21 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
