Genes affected

NDOR1 (HGNC:29838): (NADPH dependent diflavin oxidoreductase 1) This gene encodes an NADPH-dependent diflavin reductase that contains both flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) binding domains. The encoded protein catalyzes the transfer of electrons from NADPH through FAD and FMN cofactors to potential redox partners. Alternative splicing results in multiple transcript variants.

The c.247C>T (p.P83S) alteration is located in exon 3 (coding exon 3) of the NDOR1 gene. This alteration results from a C to T substitution at nucleotide position 247, causing the proline (P) at amino acid position 83 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
