Genes affected
GALNT2 (HGNC:4124): (polypeptide N-acetylgalactosaminyltransferase 2) This gene encodes a member of the glycosyltransferase 2 protein family. Members of this family initiate mucin-type O-glycoslation of peptides in the Golgi apparatus. The encoded protein may be involved in O-linked glycosylation of the immunoglobulin A1 hinge region. This gene may influence triglyceride levels, and may be involved Type 2 diabetes, as well as several types of cancer. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2022The c.215C>T (p.P72L) alteration is located in exon 2 (coding exon 2) of the GALNT2 gene. This alteration results from a C to T substitution at nucleotide position 215, causing the proline (P) at amino acid position 72 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
