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.710G>A (p.R237Q) alteration is located in exon 5 (coding exon 5) of the DDAH1 gene. This alteration results from a G to A substitution at nucleotide position 710, causing the arginine (R) at amino acid position 237 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
