Vitamin metabolism disorders v0.7 PRDX1 Bryony Thompson gene: PRDX1 was added
gene: PRDX1 was added to Inherited vitamin B12 or cobalamin deficiency. Sources: Literature
Mode of inheritance for gene: PRDX1 was set to Other
Publications for gene: PRDX1 were set to 29302025; 35190856
Phenotypes for gene: PRDX1 were set to methylmalonic aciduria and homocystinuria type cblC MONDO:0010184
Mode of pathogenicity for gene: PRDX1 was set to Other
Review for gene: PRDX1 was set to GREEN
Added comment: Only variants affecting the canonical splice acceptor site of intron 5 (e.g. c.515-1G-T, c.515-2A-T) that cause skipping of exon 6 and the polyA termination signal of PRDX1 produce an MMACHC epimutation. The resulting read-through transcript extends through the adjacent MMACHC locus in the antisense orientation. These PRDX1 exon 6 acceptor splice site variants cause disease through digenic inheritance with a pathogenic MMACHC on the other allele.
