Genes affected

DDAH1 (HGNC:2715): (dimethylarginine dimethylaminohydrolase 1) This gene belongs to the dimethylarginine dimethylaminohydrolase (DDAH) gene family. The encoded enzyme plays a role in nitric oxide generation by regulating cellular concentrations of methylarginines, which in turn inhibit nitric oxide synthase activity.

The c.119T>C (p.V40A) alteration is located in exon 1 (coding exon 1) of the DDAH1 gene. This alteration results from a T to C substitution at nucleotide position 119, causing the valine (V) at amino acid position 40 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
