Genes affected

ST8SIA6 (HGNC:23317): (ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 6) This gene encodes a member of the glycosyltransferase 29 protein family. Members of this protein family synthesize sialylglycoconjugates. Sialylation may contribute to multidrug resistance in cancer cells. Alternative splicing results in multiple transcript variants.

ST8SIA6-AS1 (HGNC:44880): (ST8SIA6 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.27).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.234 is higher than 0.05.
