Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PREPL gene is commonly pathogenic or not. These statistics are base on transcript: NM_001171613.2. 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: Probable serine peptidase whose precise substrate specificity remains unclear. Does not cleave peptides after a arginine or lysine residue. May play a role in the regulation of synaptic vesiscle exocytosis (PubMed:24610330). {ECO:0000269|PubMed:16143824, ECO:0000269|PubMed:16385448, ECO:0000269|PubMed:24610330}.;
Disease: DISEASE: Myasthenic syndrome, congenital, 22 (CMS22) [MIM:616224]: A form of congenital myasthenic syndrome, a group of disorders characterized by failure of neuromuscular transmission, including pre-synaptic, synaptic, and post-synaptic disorders that are not of autoimmune origin. Clinical features include easy fatigability and muscle weakness. CMS22 is an autosomal recessive form characterized by neonatal hypotonia. {ECO:0000269|PubMed:24610330}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
