Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the C1GALT1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000020156.5. 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: Glycosyltransferase that generates the core 1 O-glycan Gal-beta1-3GalNAc-alpha1-Ser/Thr (T antigen), which is a precursor for many extended O-glycans in glycoproteins. Plays a central role in many processes, such as angiogenesis, thrombopoiesis and kidney homeostasis development.
• Pathway: Mucin type O-glycan biosynthesis - Homo sapiens (human);Ectoderm Differentiation;Post-translational protein modification;Metabolism of proteins;mucin core 1 and core 2 <i>O</i>-glycosylation;O-linked glycosylation of mucins;O-linked glycosylation (Consensus)
