Genes affected
SLC52A1 (HGNC:30225): (solute carrier family 52 member 1) Biological redox reactions require electron donors and acceptor. Vitamin B2 is the source for the flavin in flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) which are common redox reagents. This gene encodes a member of the riboflavin (vitamin B2) transporter family. Haploinsufficiency of this protein can cause maternal riboflavin deficiency. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Jan 2013]

Ariboflavinosis Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 29, 2019In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has been reported in an individual affected with multiple acyl-CoA dehydrogenase deficiency (MADD) (PMID: 23506902). This variant is present in population databases (rs139373407, ExAC 0.06%). This sequence change replaces alanine with threonine at codon 210 of the SLC52A1 protein (p.Ala210Thr). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and threonine. -
