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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 01, 2024The c.692C>T (p.T231M) alteration is located in exon 7 (coding exon 5) of the GALNT13 gene. This alteration results from a C to T substitution at nucleotide position 692, causing the threonine (T) at amino acid position 231 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
