Genes affected

FLAD1 (HGNC:24671): (flavin adenine dinucleotide synthetase 1) This gene encodes the enzyme that catalyzes adenylation of flavin mononucleotide (FMN) to form flavin adenine dinucleotide (FAD) coenzyme. Alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jul 2008]

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 41 of the FLAD1 protein (p.Pro41Leu). This variant is present in population databases (rs375419220, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with FLAD1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In 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. -
