Sarah Leigh (Genomics England Curator)

Green List (high evidence)

Comment on mode of pathogenicity: It would appear that MAST3 variants have a gain-of-function effect (PMID:34185323).

MAST3 variants have been associated with Developmental and epileptic encephalopathy 108 (OMIM:620115). PMID:34185323 reports five de novo missense MAST3 variants in eleven unrelated individuals with developmental and epileptic encephalopathy, with a range of seizure types. These variants are within the serine-threonine kinases (STK) domain. PMID: 35095415 reports a further four de novo missense MAST3 variants, within the domain of unknown function (DUF). It would appear that the variants within the STK domain are associated with a neurodevelopmental disorder with a epilepsy phenotype, while variants within the DUF domain have a autistic spectrum disorder phenotype (PMID: 35095415)
Functional studies suggest that the MAST3 variants have a gain-of-function effect (PMID:34185323; 35095415).
