Mendeliome v1.3981 UNC13A Zornitza Stark edited their review of gene: UNC13A: Added comment: PMID 41125872 reports 48 individuals with neurodevelopmental disorders and UNC13A variants. Of these, 20 classified as pathogenic. Of these 6 individuals had biallelic variants and presented with severe-to-profound GDD or intellectual disability, hypotonia and seizures of different types (largely controllable with medication) or death in early childhood caused by respiratory failure after pneumonia in one case. Mechanism for this subgroup is LoF with carrier parents unaffected.

A second group of 13 patients (21 months to 32 years old) harboured pathogenic, heterozygous de novo missense variants with multiple substitutions at amino acids 808, 811 and 814 (hinge region). They presented with variable degrees of GDD, hypotonia, seizures of different types (mainly refractory to treatment) and typically exhibited ataxia, tremor or dyskinetic movements rarely observed in other patients.

Also a family identified with at least four affected members across two generations (4 years to 35 years old) harbouring a pathogenic heterozygous missense variant (C587F) that caused learning difficulties to mild–moderate intellectual disability as well as controlled seizures.

Three different types of mechanism of pathogenicity proposed.; Changed rating: GREEN; Changed publications: 27648472, 28192369, 41125872; Changed phenotypes: neurodevelopmental disorder MONDO#0700092, UNC13A-related, Neurodevelopmental disorder with hypotonia, epilepsy, and absent speech, MIM# 621455
