The H459Y missense change has not been published as a pathogenic variant, nor has it been reported as a benign polymorphism to our knowledge. The 1000 Genomes Database reports H459Y was observed in 2/186 (1.08%) alleles from individuals of Finnish background. The amino acid change is non-conservative in that a positively charged Histidine residue is replaced by an uncharged Tyrosine residue. This change occurs at a highly conserved position in the ETFDH protein, and multiple in-silico analysis models predict that H459Y is damaging to the ETFDH protein. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
