Genes affected

HAL (HGNC:4806): (histidine ammonia-lyase) Histidine ammonia-lyase is a cytosolic enzyme catalyzing the first reaction in histidine catabolism, the nonoxidative deamination of L-histidine to trans-urocanic acid. Histidine ammonia-lyase defects cause histidinemia which is characterized by increased histidine and histamine and decreased urocanic acid in body fluids. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

Three heterozygous loss-of-function variants in HAL were found in 24/1152 African American individuals, in association with elevated serum histidine levels. Histidine level is a potential predictor of cardiovascular risk. Thus, loss-of-function variants in HAL may modify cardiovascular risk. Findings were replicated in a European American cohort. -
