Genes affected

DOHH (HGNC:28662): (deoxyhypusine hydroxylase) This gene encodes a metalloenzyme that catalyzes the last step in the conversion of lysine to the unique amino acid hypusine in eukaryotic initiation factor 5A. The encoded protein hydroxylates deoxyhypusine to form hypusine in the mature eukaryotic initiation factor 5A protein. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Feb 2009]

Nov 26, 2024

The c.766G>A (p.A256T) alteration is located in exon 5 (coding exon 4) of the DOHH gene. This alteration results from a G to A substitution at nucleotide position 766, causing the alanine (A) at amino acid position 256 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
