Fetal anomalies v2.10 ATAD3A Arina Puzriakova Tag Q3_21_MOI was removed from gene: ATAD3A.
Fetal anomalies v2.10 ATAD3A Arina Puzriakova commented on gene: ATAD3A: The mode of inheritance of this gene has been updated to 'BOTH monoallelic and biallelic, autosomal or pseudoautosomal' following NHS Genomic Medicine Service approval.
Fetal anomalies v2.9 ATAD3A Arina Puzriakova Source NHS GMS was added to ATAD3A.
Mode of inheritance for gene ATAD3A was changed from MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted to BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Fetal anomalies v1.684 ATAD3A Arina Puzriakova Publications for gene: ATAD3A were set to 27640307; 28327206
Fetal anomalies v1.683 ATAD3A Arina Puzriakova Phenotypes for gene: ATAD3A were changed from ATAD3A disorder - global developmental delay, hypotonia, optic atrophy, axonal neuropathy, and hypertrophic cardiomyopathy; ATAD3A disorder - global developmental delay, hypotonia, optic atrophy, axonal neuropathy, and hypertrophic cardiomyopathy; Harel-Yoon syndrome, 617183 to ATAD3A disorder - global developmental delay, hypotonia, optic atrophy, axonal neuropathy, and hypertrophic cardiomyopathy; Harel-Yoon syndrome, OMIM:617183; Pontocerebellar hypoplasia, hypotonia, and respiratory insufficiency syndrome, neonatal lethal, OMIM:618810
Fetal anomalies v1.682 ATAD3A Arina Puzriakova Tag watchlist was removed from gene: ATAD3A.
Tag Q3_21_MOI tag was added to gene: ATAD3A.
Fetal anomalies v1.682 ATAD3A Arina Puzriakova Added comment: Comment on mode of inheritance: MOI should be updated from 'Monoallelic' to 'Both mono- and biallelic' at the next GMS panel review.

At least 7 unrelated families have now been reported with biallelic SNVs in ATAD3A, including 5 families with Harel-Yoon syndrome, MIM# 617183 (PMID: 27640307; 32607449; 33845882) and 2 families with neonatal lethal pontocerebellar hypoplasia, MIM# 618810 (PMID: 29053797; 31727539). Both of these phenotypes are pertinent to this panel.
Fetal anomalies v1.682 ATAD3A Arina Puzriakova Mode of inheritance for gene: ATAD3A was changed from MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Fetal anomalies v0.161 ATAD3A Rebecca Foulger edited their review of gene: ATAD3A: Added comment: This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in March 2019. Clinical review and curation was performed by Lyn Chitty, Anna de Burca, Rhiannon Mellis, Richard Scott, Ellen McDonagh and Rebecca Foulger. Outcome of review: Confirmed that phenotype is fetally-relevant: keep on the Fetal anomalies panel as a Green gene.; Changed rating: GREEN
Fetal anomalies v0.55 ATAD3A Rebecca Foulger Mode of pathogenicity for gene: ATAD3A was changed from to Loss-of-function variants (as defined in pop up message) DO NOT cause this phenotype - please provide details in the comments
Fetal anomalies v0.54 ATAD3A Rebecca Foulger Added comment: Comment on mode of inheritance: Changed MOI from 'Both monoallelic and biallelic' to only monoallelic, based on Anna's review: Green rating is appropriate for monoallelic inheritance only as there is currently insufficient evidence for biallelic disorder.
Fetal anomalies v0.54 ATAD3A Rebecca Foulger Mode of inheritance for gene: ATAD3A was changed from BOTH monoallelic and biallelic, autosomal or pseudoautosomal to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Fetal anomalies v0.53 ATAD3A Rebecca Foulger Classified gene: ATAD3A as Green List (high evidence)
Fetal anomalies v0.53 ATAD3A Rebecca Foulger Added comment: Comment on list classification: Updated rating from Amber to Green following review from Anna de Burca. Originally assigned an Amber rating because of different PAGE/DDG2P ratings for different disorders. Green rating is appropriate for monoallelic inheritance only, as stated in Anna's review.
Fetal anomalies v0.53 ATAD3A Rebecca Foulger Gene: atad3a has been classified as Green List (High Evidence).
Fetal anomalies v0.52 ATAD3A Rebecca Foulger Publications for gene: ATAD3A were set to
Fetal anomalies v0.51 ATAD3A Rebecca Foulger Phenotypes for gene: ATAD3A were changed from ATAD3A disorder - global developmental delay, hypotonia, optic atrophy, axonal neuropathy, and hypertrophic cardiomyopathy; ATAD3A disorder - global developmental delay, hypotonia, optic atrophy, axonal neuropathy, and hypertrophic cardiomyopathy to ATAD3A disorder - global developmental delay, hypotonia, optic atrophy, axonal neuropathy, and hypertrophic cardiomyopathy; ATAD3A disorder - global developmental delay, hypotonia, optic atrophy, axonal neuropathy, and hypertrophic cardiomyopathy; Harel-Yoon syndrome, 617183
Fetal anomalies v0.34 ATAD3A Anna de Burca commented on gene: ATAD3A: PMID: 27640307 reports a recurrent de novo variant in ATAD3A in five unrelated individuals with developmental delay and hypotonia. Some individuals had peripheral neuropathy, optic atrophy and hypertrophic cardiomyopathy. A toxic gain of function mechanism was postulated. PMID: 28327206 reports an additional case with the same de novo variant. This individual had delayed motor development and hypotonia. PMID: 27640307 also reports a biallelic missense variant in siblings of distantly related parents with motor and speech delay, hypotonia, cerebellar atrophy, ataxia, seizures, muscle weakness, cataracts and optic nerve hypoplasia. There is insufficient evidence for this association at present. Therefore, this gene should be classified green with regard to monoallelic gain of function only.
