Labcorp Genetics (formerly Invitae), Labcorp RCV001300175 SCV001489301 uncertain significance Deficiency of 3-hydroxyacyl-CoA dehydrogenase 2022-02-10 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1003601). This variant has not been reported in the literature in individuals affected with HADH-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 242 of the HADH protein (p.Glu242Gly). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Clinical Genomics, Uppaluri K&H Personalized Medicine Clinic RCV003222294 SCV003915751 likely risk allele Hyperinsulinemic hypoglycemia criteria provided, single submitter research Potent mutations in HADH gene are associated with congenital hyperinsulinism, which leads to recurrent hypoglycemia. The condition is exacerbated by stress, fasting or excessive dietary protein. May respond well to diazoxide. However, the role of this particular variant rs1736337186 in congenital hyperinsulinism is yet to be ascertained.
