Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the BCHE 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: Esterase with broad substrate specificity. Contributes to the inactivation of the neurotransmitter acetylcholine. Can degrade neurotoxic organophosphate esters. {ECO:0000269|PubMed:19452557, ECO:0000269|PubMed:19542320}.
• Disease: DISEASE: Butyrylcholinesterase deficiency (BCHED) [MIM:617936]: An autosomal recessive metabolic condition characterized by increased sensitivity to certain anesthetic drugs, including the muscle relaxants succinylcholine or mivacurium. BCHED results in slower hydrolysis of these drugs and, consequently, a prolonged neuromuscular block, leading to apnea. The duration of the prolonged apnea varies significantly depending on the extent of the enzyme deficiency. {ECO:0000269|PubMed:10404729, ECO:0000269|PubMed:11928765, ECO:0000269|PubMed:12881446, ECO:0000269|PubMed:1306123, ECO:0000269|PubMed:1349196, ECO:0000269|PubMed:1415224, ECO:0000269|PubMed:15563885, ECO:0000269|PubMed:15781196, ECO:0000269|PubMed:1611188, ECO:0000269|PubMed:16788378, ECO:0000269|PubMed:17700357, ECO:0000269|PubMed:18075469, ECO:0000269|PubMed:18300943, ECO:0000269|PubMed:25054547, ECO:0000269|PubMed:25264279, ECO:0000269|PubMed:2915989, ECO:0000269|PubMed:7634491, ECO:0000269|PubMed:8554068, ECO:0000269|PubMed:8680411, ECO:0000269|PubMed:9110359, ECO:0000269|PubMed:9191541, ECO:0000269|PubMed:9388484, ECO:0000269|PubMed:9543549, ECO:0000269|PubMed:9694584}.
