Intellectual disability - microarray and sequencing v3.1519 ABHD16A Ivone Leong Tag Q4_21_rating was removed from gene: ABHD16A.
Intellectual disability - microarray and sequencing v3.1519 ABHD16A Sarah Leigh commented on gene: ABHD16A
Intellectual disability - microarray and sequencing v3.1519 ABHD16A Ivone Leong Source Expert Review Green was added to ABHD16A.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Intellectual disability - microarray and sequencing v3.1359 ABHD16A Ivone Leong Tag Q4_21_rating tag was added to gene: ABHD16A.
Intellectual disability - microarray and sequencing v3.1359 ABHD16A Ivone Leong Classified gene: ABHD16A as Amber List (moderate evidence)
Intellectual disability - microarray and sequencing v3.1359 ABHD16A Ivone Leong Added comment: Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is not associated with a phenotype in OMIM or Gene2Phenotype. There are >3 unrelated cases, therefore there is enough evidence to support a gene-disease association. This gene should be rated Green at the next review.
Intellectual disability - microarray and sequencing v3.1359 ABHD16A Ivone Leong Gene: abhd16a has been classified as Amber List (Moderate Evidence).
Intellectual disability - microarray and sequencing v3.1334 ABHD16A Zornitza Stark gene: ABHD16A was added
gene: ABHD16A was added to Intellectual disability. Sources: Literature
Mode of inheritance for gene: ABHD16A was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: ABHD16A were set to 34587489
Phenotypes for gene: ABHD16A were set to Spastic paraplegia; Intellectual disability
Review for gene: ABHD16A was set to GREEN
gene: ABHD16A was marked as current diagnostic
Added comment: 11 individuals from 6 families with a complicated form of hereditary spastic paraplegia who carry bi-allelic deleterious variants in ABHD16A. Affected individuals present with a similar phenotype consisting of global developmental delay/intellectual disability, progressive spasticity affecting the upper and lower limbs, and corpus callosum and white matter anomalies. Immunoblot analysis on extracts from fibroblasts from four affected individuals demonstrated little to no ABHD16A protein levels compared to controls.
In 5 of the families the affected members were homozygous, 3 of these families were consanguineous. 2 families have the same variant- both families are French-Canadian.
4 missense variants, 1 frameshift, 1 nonsense.
