Genetic Epilepsy v0.2149 DOHH Andrew Fennell gene: DOHH was added
gene: DOHH was added to Genetic Epilepsy. Sources: Literature
Mode of inheritance for gene: DOHH was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: DOHH were set to PMID: 30661771; 35858628
Phenotypes for gene: DOHH were set to Neurodevelopmental disorder, DOHH-related (MONDO#0700092)
Review for gene: DOHH was set to GREEN
Added comment: PMID: 35858628 - three of the five reported individuals with this neurodevelopmental disorder identified to have seizures. Two individuals had febrile seizures in mid-childhood with one going on to have generalised epilepsy. A third individual had generalised epilepsy.

PMID: 30661771 - Of note, DOHH is a key part of the same two-step enzymatic pathway as DHPS which is also associated with a neurodevelopmental disorder that prominently features seizures.

Genetic Epilepsy v0.239 DHPS Zornitza Stark gene: DHPS was added
gene: DHPS was added to Genetic Epilepsy. Sources: Expert list
Mode of inheritance for gene: DHPS was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: DHPS were set to 30661771
Phenotypes for gene: DHPS were set to Neurodevelopmental disorder with seizures and speech and walking impairment, MIM#618480
Review for gene: DHPS was set to GREEN
gene: DHPS was marked as current diagnostic
Added comment: 5 individuals from 4 unrelated families with biallelic pathogenic variants in DHPS, note one variant is recurrent (c.518A>G or p.Asn173Ser). The phenotype consisted of DD/ID (5/5), tone abnormalities (hypotonia/hypertonia/spasticity - 5/5), seizures (5/5 - in one case though unclear staring spells) with EEG abnormalities (5/5). Additionally most individuals displayed behavioral issues, or some common facial features.
