Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the CSAD gene is commonly pathogenic or not. These statistics are base on transcript: NM_001244705.2. 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: Catalyzes the decarboxylation of L-aspartate, 3-sulfino- L-alanine (cysteine sulfinic acid), and L-cysteate to beta- alanine, hypotaurine and taurine, respectively. The preferred substrate is 3-sulfino-L-alanine. Does not exhibit any decarboxylation activity toward glutamate. {ECO:0000250|UniProtKB:Q9DBE0}.;
