Description

The AKT3 c.1393C>T variant is predicted to result in the amino acid substitution p.Arg465Trp. This variant has been reported de novo in multiple individuals with megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome 2 (Rivière et al. 2012. PMID: 22729224, Table 1 Alacantara et al. 2017. PMID: 28969385, eTable 3 Meng et al. 2017. PMID: 28973083, S Table 1 Tumiene et al. 2018. PMID: 29286531, Table 1 Lin et al. 2020 PMID: 33176815, Results section 3.3.2 Moirangthem et al 2021 PMID: 33942996.) This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. This variant is interpreted as pathogenic.
