Early onset or syndromic epilepsy v4.14 OTUD7A Achchuthan Shanmugasundram changed review comment from: PMID:31997314 reported a patient presenting with severe global developmental delay, language impairment and epileptic encephalopathy and was identified with homozygous variant in OTUD7A gene (c.697C>T)/ p.Leu233Phe).

PMID:33381903 reported a patient with profound hypotonia, severe intellectual disability, and seizures and identified with biallelic loss-of-function variants in OTUD7A: a 15q13.3 deletion including the OTUD7A locus, and a frameshift OTUD7A variant c.1125del/ p.Glu375Aspfs*11.

PMID:36180924 reported a patient (patient #4) presenting with severe neurodevelopmental diseases and dysmorphic features and identified with hemizygous OTUD7A frameshift variant allele c.2023_2066del/ p.D675Hfs*188 in trans with the recurrent 15q13.3 BP4-BP5 deletion.

This gene has been reported in the DD panel of Gene2Phenotype (with 'limited' rating), but has not yet been associated with phenotypes in OMIM.

OTUD7A knockout mice exhibited reduced body weight, developmental delay, abnormal electroencephalography patterns and seizures, reduced ultrasonic vocalisations, decreased grip strength, impaired motor learning/motor coordination, and reduced acoustic startle (PMID:29395075). The function evidence also suggest that OTUD7A may be the critical “driver gene” in the 15q13.3 deletion syndrome.; to: PMID:31997314 reported a patient presenting with severe global developmental delay, language impairment and epileptic encephalopathy and was identified with homozygous variant in OTUD7A gene (c.697C>T)/ p.Leu233Phe).

Early onset or syndromic epilepsy v2.119 OTUD7A Sarah Leigh commented on gene: OTUD7A: Review by Zornitza Stark on Intellectual disability panel https://panelapp.genomicsengland.co.uk/panels/285/: One patient with severe global developmental delay, language impairment and epileptic encephalopathy reported. Homozygous OTUD7A missense variant (c.697C>T, p.Leu233Phe), predicted to alter an ultraconserved amino acid, lying within the OTU catalytic domain. Its subsequent segregation analysis revealed that the parents, presenting with learning disability, and brother were heterozygous carriers. Biochemical assays demonstrated that proteasome complex formation and function were significantly reduced in patient‐derived fibroblasts and in OTUD7A knockout HAP1 cell line. Gene lies in the chromosome 15q13.3 region. Heterozygous microdeletions of chromosome 15q13.3 show incomplete penetrance and are associated with a highly variable phenotype that may include intellectual disability, epilepsy, facial dysmorphism and digit anomalies. Mouse model and other data support the role of this gene in neurodevelopmental phenotypes but nevertheless, single family to date.
Early onset or syndromic epilepsy v2.119 OTUD7A Sarah Leigh gene: OTUD7A was added

Phenotypes for gene: OTUD7A were set to Epileptic encephalopathy, intellectual disability
Review for gene: OTUD7A was set to RED
Added comment: Not associated with phenotype in OMIM or in Gen2Phen, Although the region ISCA-46295-Loss, which encompasses the OTUD7A locus, is associated with seizures 20236110, mental retardation 22775350, dysmorphic features, developmental delay and severe epileptic encephalopathy. PMID 31997314 report a homozygous variant in a case of severe global developmental delay, language impairment and epileptic encephalopathy; segregation and functional studies support this gene disease association.
