Intellectual disability syndromic and non-syndromic v0.1327 PHF21A Chirag Patel Classified gene: PHF21A as Green List (high evidence)
Intellectual disability syndromic and non-syndromic v0.1327 PHF21A Chirag Patel Gene: phf21a has been classified as Green List (High Evidence).
Intellectual disability syndromic and non-syndromic v0.1326 PHF21A Chirag Patel gene: PHF21A was added
gene: PHF21A was added to Intellectual disability, syndromic and non-syndromic_GHQ_VCGS. Sources: Literature
Mode of inheritance for gene: PHF21A was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: PHF21A were set to PMID: 31649809; 30487643; 22770980
Phenotypes for gene: PHF21A were set to no OMIM number yet.
Review for gene: PHF21A was set to GREEN
Added comment: 9 cases with intellectual disability and craniofacial anomalies (Potocki-Shaffer syndrome), with de novo truncating variants in PHF21A. No functional evidence of variants, but PHF21A is highly expressed in the human fetal brain, which is consistent with the neurodevelopmental phenotype.

2 other unrelated individuals with translocations disrupting PHF21A. Lymphoblastoid cell lines from translocation subjects showed derepression of the neuronal gene SCN3A and reduced LSD1 occupancy at the SCN3A promoter, supporting a direct functional consequence of PHF21A haploinsufficiency on transcriptional regulation.
