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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2023The c.1045A>C (p.T349P) alteration is located in exon 8 (coding exon 8) of the ST8SIA6 gene. This alteration results from a A to C substitution at nucleotide position 1045, causing the threonine (T) at amino acid position 349 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
