Genes affected
ALDH6A1 (HGNC:7179): (aldehyde dehydrogenase 6 family member A1) This gene encodes a member of the aldehyde dehydrogenase protein family. The encoded protein is a mitochondrial methylmalonate semialdehyde dehydrogenase that plays a role in the valine and pyrimidine catabolic pathways. This protein catalyzes the irreversible oxidative decarboxylation of malonate and methylmalonate semialdehydes to acetyl- and propionyl-CoA. Methylmalonate semialdehyde dehydrogenase deficiency is characterized by elevated beta-alanine, 3-hydroxypropionic acid, and both isomers of 3-amino and 3-hydroxyisobutyric acids in urine organic acids. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jun 2013]
BBOF1 (HGNC:19855): (basal body orientation factor 1) Predicted to be involved in motile cilium assembly. Predicted to be located in ciliary basal body. [provided by Alliance of Genome Resources, Apr 2022]
