Undiagnosed metabolic disorders
Gene: ATAD3AComment on mode of inheritance: Changed MOI from 'Biallelic' to 'Both mono- and biallelic'.
At least 6 families with heterozygous variants (PMID: 27640307; 28158749) and 7 unrelated families with biallelic SNVs in this gene (PMID: 27640307; 29053797; 31727539; 32607449; 33845882). Metabolic evaluation often show elevated 3-methylglutaconate and lactate in patients with variants in this gene.Created: 6 Jul 2021, 9:41 a.m. | Last Modified: 6 Jul 2021, 9:41 a.m.
Panel Version: 1.465
As a result of watchlist tag audit the watchlist tag was removed from ATAD3A this is now a green gene with sufficient evidence/review. The gene is also now rated Green on the intellectual disability panel.Created: 13 Jan 2020, 4:55 p.m. | Last Modified: 13 Jan 2020, 4:55 p.m.

Comment on list classification: New gene added by external expert and reviewed by curation team and the clinical team: Sufficient evidence has been provided by the external expert review for this gene to be rated green.
Other aspects of the phenotype may warrant for this gene to be included on alternative specific panels (i.e. intellectual disability); however, not enough evidence is available at the moment. Therefore, this gene has also been added to the "watchlist" so that more cases can be collected.Created: 18 Mar 2019, 3 p.m.
Comment on mode of pathogenicity: There is a recurrent missense variant thought to act in a dominant negative manner.Created: 18 Mar 2019, 2:40 p.m.
Comment on mode of inheritance: As the carrier parents of the biallelic cases do not appear to have any phenotype, have given this a biallelic mode of inheritance.Created: 18 Mar 2019, 2:38 p.m.
A raised plasma lactate was reported in 4/7 families and methylglutaconic aciduria in 3/7 families (PMID: 27640307). Multiple patients with a diagnosis are described as having "severe metabolic disease".
