Genes affected

CSGALNACT2 (HGNC:24292): (chondroitin sulfate N-acetylgalactosaminyltransferase 2) This gene encodes a member of the chondroitin N-acetylgalactosaminyltransferase family. The encoded protein is involved in elongation during chondroitin sulfate synthesis. Alternative splicing of this gene results in multiple transcript variants. Two related pseudogenes have been identified on chromosome X. [provided by RefSeq, Feb 2016]

The c.580C>T (p.P194S) alteration is located in exon 2 (coding exon 1) of the CSGALNACT2 gene. This alteration results from a C to T substitution at nucleotide position 580, causing the proline (P) at amino acid position 194 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
