acetyl-CoA carboxylase alpha

Also known as: ACAC, ACACAD, ACACalpha, ACC, ACC1, ACCA, ACCalpha, Acac1

Acetyl-CoA carboxylase alpha catalyzes the carboxylation of acetyl-CoA to malonyl-CoA, the rate-limiting step in fatty acid synthesis. Biallelic mutations cause acetyl-CoA carboxylase deficiency with autosomal recessive inheritance. The gene is highly constrained against loss-of-function variants, indicating that functional copies are critical for normal development.

Clinical SummaryACACA
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.
