Genes affected
HADHA (HGNC:4801): (hydroxyacyl-CoA dehydrogenase trifunctional multienzyme complex subunit alpha) This gene encodes the alpha subunit of the mitochondrial trifunctional protein, which catalyzes the last three steps of mitochondrial beta-oxidation of long chain fatty acids. The mitochondrial membrane-bound heterocomplex is composed of four alpha and four beta subunits, with the alpha subunit catalyzing the 3-hydroxyacyl-CoA dehydrogenase and enoyl-CoA hydratase activities. Mutations in this gene result in trifunctional protein deficiency or LCHAD deficiency. The genes of the alpha and beta subunits of the mitochondrial trifunctional protein are located adjacent to each other in the human genome in a head-to-head orientation.

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The G328R missense substitution has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The amino acid change is non-conservative as a small, uncharged Glycine residue is replaced by a large, positively charged Arginine residue. This change occurs at a highly conserved position in the HADHA protein. In-silico analyses are not consistent in their predictions of whether G328R is damaging to the HADHA protein. Therefore, based on the currently available information, it is unclear whether G328R is a disease-causing mutation or a rare benign variant. The variant is found in HADHA panel(s). -

Variant summary: HADHA c.982G>A (p.Gly328Arg) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 251214 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.982G>A has been reported in the literature in one individual affected with Long Chain 3-Hydroxyacyl-CoA Dehydrogenase Deficiency (Djouadi_2016, Schwantje_2022). These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 26109258, 35383965). ClinVar contains an entry for this variant (Variation ID: 203744). Based on the evidence outlined above, the variant was classified as uncertain significance. -
