Intellectual disability syndromic and non-syndromic v0.2750 ABCA2 Konstantinos Varvagiannis gene: ABCA2 was added
gene: ABCA2 was added to Intellectual disability syndromic and non-syndromic. Sources: Literature
Mode of inheritance for gene: ABCA2 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: ABCA2 were set to 30237576; 29302074; 31047799
Phenotypes for gene: ABCA2 were set to Intellectual developmental disorder with poor growth and with or without seizures or ataxia, 618808
Penetrance for gene: ABCA2 were set to Complete
Review for gene: ABCA2 was set to GREEN
Added comment: Biallelic pathogenic ABCA2 variants cause Intellectual developmental disorder with poor growth and with or without seizures or ataxia (MIM 618808).

There are 3 relevant publications (01-07-2020) :
- Maddirevula et al [2019 - PMID: 30237576] described briefly 2 unrelated subjects (16-2987, 16DG0071) both DD and seizures among other manifestations.
- Hu et al [2019 - PMID: 29302074] reported 3 sibs (M8600615 - III:1-3) born to consanguineous parents (M8600615 - III:1-3) with DD/ID (formal confirmation of moderate ID, in those (2) evaluated). One also presented with seizures.
- Aslam and Naz [2019 - PMID: 31047799] provided clinical details on 2 siblings born to consanguineous parents. ID was reported for the older sib but was absent in the younger one. Seizures were not part of the phenotype.

All subjects harbored biallelic pLoF variants.

N.B. : Steinberg et al [2015 - PMID: 25773295], within a cohort of patients with ALS, identified one with biallelic ABCA2 variants. As however Aslam and Naz comment, this person harbored a single pathogenic variant, with a second one rather unlikely to be pathogenic due to high allele frequency.

Overall this gene can be considered for inclusion with green rating in both ID and epilepsy panels (each in >=3 unrelated individuals).
