Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the POGLUT1 gene is commonly pathogenic or not.

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: Dual specificity glycosyltransferase that catalyzes the transfer of glucose and xylose from UDP-glucose and UDP-xylose, respectively, to a serine residue found in the consensus sequence of C-X-S-X-P-C (PubMed:21081508, PubMed:21490058, PubMed:21949356, PubMed:27807076, PubMed:28775322). Specifically targets extracellular EGF repeats of protein such as CRB2, F7, F9 and NOTCH2 (PubMed:21081508, PubMed:21490058, PubMed:21949356, PubMed:27807076, PubMed:28775322). Acts as a positive regulator of Notch signaling by mediating O-glucosylation of Notch, leading to regulate muscle development (PubMed:27807076). Notch glucosylation does not affect Notch ligand binding (PubMed:21490058). Required during early development to promote gastrulation: acts by mediating O-glucosylation of CRB2, which is required for CRB2 localization to the cell membrane (By similarity). {ECO:0000250|UniProtKB:Q8BYB9, ECO:0000269|PubMed:21081508, ECO:0000269|PubMed:21490058, ECO:0000269|PubMed:21949356, ECO:0000269|PubMed:27807076, ECO:0000269|PubMed:28775322}.
• Disease: DISEASE: Limb-girdle muscular dystrophy 2Z (LGMD2Z) [MIM:617232]: A form of autosomal recessive limb-girdle muscular dystrophy, a degenerative myopathy characterized by slowly progressive wasting and weakness of the proximal muscles of arms and legs around the pelvic or shoulder girdles, elevated creatine kinase levels and dystrophic features on muscle biopsy. LGMD2Z is characterized by young-adult onset. {ECO:0000269|PubMed:27807076}. Note=The disease is caused by mutations affecting the gene represented in this entry.
