Notes
aka c.944G>A (p.Arg315His, R315H) Annotated in ClinVar as benign; described in OMIM as having "nearly normal properties" 23andMe name: i5053909 FTDNA & MyHeritage name: VGXS34738
C;T
Carrier of a variant considered benign; see rs-page for details.
T;T
Even if asymptomatic, consider being tested for G6PD deficiency and be aware of hemolytic anemia potential when taking certain drugs. See G6PD gene page for more information.
