DGKE and homocystinuria: A complete gene panel test should also include heterozygous or homozygous pathogenic variants of diacylglycerol kinase epsilon (DGKE), methylmalonic aciduria and homocystinuria, cobalamin C (MMACHC), C3, CD46, CFB, CFH, CFD, and CFI as well as homozygous deletions of the CFHR genes (typically CFHR1–3 and 5) [1,2,3].
