Enables hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in cyclic amides. Involved in pyrimidine nucleobase catabolic process. Located in cytoplasm. Expressed in body wall musculature. Human ortholog(s) of this gene implicated in Ritscher-Schinzel syndrome; dihydropyrimidinase deficiency; and purine-pyrimidine metabolic disorder. Is an ortholog of human DPYS (dihydropyrimidinase).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
