Achchuthan Shanmugasundram gene: PLXNA1 was added gene: PLXNA1 was added to Early onset or syndromic epilepsy. Sources: Literature Mode of inheritance for gene: PLXNA1 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: PLXNA1 were set to 28464511; 34054129 Phenotypes for gene: PLXNA1 were set to developmental and epileptic encephalopathy, MONDO:0100062 Review for gene: PLXNA1 was set to GREEN Added comment: Monoallelic cases: PMID:28464511 reported a male patient with a de novo variant in PLXNA1 and presenting with intractable infantile onset epilepsy, and intellectual disability with autism spectrum disorder. In addition, this patient also had features suggestive of Dubowitz syndrome, including growth failure, dermatologic symptoms, and characteristic dysmorphic facial features. It has also been reviewed in this publication that one of only two previously reported cases with missense PLXNA1 variants had epileptic encephalopathy. PMID:34054129 reported ten cases from seven families with PLXNA1 variants. Of these cases, three unrelated cases had monoallelic de novo variants and presented with global developmental delay, seizures and craniofacial, brain and eye anomalies. Biallelic cases: Out of ten cases reported in PMID:34054129, seven cases from four unrelated families exhibited biallelic variants in PLXNA1 gene. They presented with global developmental delay and craniofacial, brain and eye anomalies. However, seizures are not reported in biallelic cases except one family (15 episodes of febrile and nonfebrile seizures reported in family A). The biallelic variants in this gene has been associated with phenotypes in OMIM (MIM #619955). However, both monoalellic and biallelic variants in this gene has been associated with phenotypes in Gene2Phenotype (with 'limited' rating). Functional studies: Structural modeling of missense variants in PLXNA1 suggests distortion in the native protein. Knockdown of plxna1a leads to cerebral anomalies and eye anomalies in zebrafish larvae. Sources: Literature |
