Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the GALNT13 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000052917.4. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function: FUNCTION: Catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D- galactosamine residue to a serine or threonine residue on the protein receptor. Has a much stronger activity than GALNT1 to transfer GalNAc to mucin peptides, such as Muc5Ac and Muc7. Able to glycosylate SDC3. May be responsible for the synthesis of Tn antigen in neuronal cells.;
Pathway: Mucin type O-glycan biosynthesis - Homo sapiens (human);Post-translational protein modification;Metabolism of proteins;mucin core 1 and core 2 <i>O</i>-glycosylation;O-Glycan biosynthesis;O-linked glycosylation of mucins;O-linked glycosylation (Consensus)
