| Dystonia, chorea or related movement disorder, childhood onset v8.10 | GTPBP1 |
Achchuthan Shanmugasundram gene: GTPBP1 was added gene: GTPBP1 was added to Childhood onset dystonia, chorea or related movement disorder. Sources: Literature Mode of inheritance for gene: GTPBP1 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: GTPBP1 were set to 38118446 Phenotypes for gene: GTPBP1 were set to Neurodevelopmental disorder with characteristic facial and ectodermal features and tetraparesis 1, OMIM:620888; neurodevelopmental disorder with characteristic facial and ectodermal features and tetraparesis 1, MONDO:0975745 Review for gene: GTPBP1 was set to AMBER Added comment: PMID:38118446 (2024) reported a cohort of 20 individuals from 16 families with distinct neurodevelopmental disorders (NDDs) and syndromic facial features and identified with biallelic variants in either GTPBP1 or GTPBP2 genes. Of these, four patients from three unrelated families were identified with homozygous variants in GTPBP1 gene. Two families have different NMD-predicted nonsense variants and the third has a missense variant, and all are absent from gnomad v4.1.1. The shared clinical features of the syndrome include microcephaly, severe/ profound neurodevelopmental impairment, pathognomonic craniofacial features, and ectodermal defects. In addition, abnormal vision and/or hearing, progressive spasticity, choreoathetoid movements, refractory epilepsy, and brain atrophy were part of the core phenotype of this syndrome. Abnormal hand movements and tremor of hands and jaws were reported in 2 patients from 2 families with GTPBP1 variants. This gene has been associated with relevant phenotypes in OMIM (MIM #620888, last accessed 29 July 2026) and in Gene2Phenotype ('moderate' rating on the DD panel). Sources: Literature |
