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]
GALNT13-AS1 (HGNC:56700): (GALNT13 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.1465G>C (p.G489R) alteration is located in exon 12 (coding exon 10) of the GALNT13 gene. This alteration results from a G to C substitution at nucleotide position 1465, causing the glycine (G) at amino acid position 489 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
