Genes affected

UROC1 (HGNC:26444): (urocanate hydratase 1) This gene encodes an enzyme involved in the second step of histidine catabolism, metabolizing urocanic acid to formiminoglutamic acid. Deficiency of this enzyme results in urocanic aciduria, and is an apparent cause of mental retardation. Multiple transcript variants encoding different isoforms have been found for this gene.

Ambry Genetics

Mar 20, 2023

The c.1846G>A (p.E616K) alteration is located in exon 19 (coding exon 19) of the UROC1 gene. This alteration results from a G to A substitution at nucleotide position 1846, causing the glutamic acid (E) at amino acid position 616 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
