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]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.71).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.243 is higher than 0.05.
