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]

Ambry Genetics

Sep 30, 2024

The c.88C>A (p.L30I) 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 88, causing the leucine (L) at amino acid position 30 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
