Genes affected
GALNT13 (HGNC:23242): (polypeptide N-acetylgalactosaminyltransferase 13) The GALNT13 protein is a member of the UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase (GalNAcT; EC 2.4.1.41) family, which initiate O-linked glycosylation of mucins (see MUC3A, MIM 158371) by the initial transfer of N-acetylgalactosamine (GalNAc) with an alpha-linkage to a serine or threonine residue.[supplied by OMIM, Apr 2004]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 05, 2023The c.358G>A (p.V120I) alteration is located in exon 5 (coding exon 3) of the GALNT13 gene. This alteration results from a G to A substitution at nucleotide position 358, causing the valine (V) at amino acid position 120 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
