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]

The c.85G>T (p.V29F) alteration is located in exon 1 (coding exon 1) of the FLAD1 gene. This alteration results from a G to T substitution at nucleotide position 85, causing the valine (V) at amino acid position 29 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
