| Childhood onset dystonia, chorea or related movement disorder v7.19 | PTPN1 |
Ida Ertmanska gene: PTPN1 was added gene: PTPN1 was added to Childhood onset dystonia, chorea or related movement disorder. Sources: Literature Q1_26_promote_green tags were added to gene: PTPN1. Mode of inheritance for gene: PTPN1 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: PTPN1 were set to 10066179; 39986310 Phenotypes for gene: PTPN1 were set to Encephalopathy, HP:0001298; dystonia, early-onset, and/or spastic paraplegia, MONDO:0859215 Review for gene: PTPN1 was set to GREEN Added comment: PMID: 39986310 Zhu et al., 2025 Reported heterozygous PTPN1 variants in 12 patients from 11 families. 2/10 were canonical splice variants, 2 were missense variants, and 6 were STOP-gain. 3 cases were de novo, 9 individuals inherited the variant from an asymptomatic parent. Sequencing method: WES + Sanger. Phenotype: 12/12 individuals experienced subacute loss of skills (age range 15 months to 8 years) after initial normal development in 11 of 12 (one patient had mild motor delay); weakness (12/12), spasticity (initially manifesting as a hemiparesis in seven patients and then becoming bilateral) +/- dystonia, bulbar involvement (dysphagia and/or dysphasia) in 11/12 patients; absence of seizures. In 4/12 patients, fever and raised liver enzymes were noted around the time of presentation. Brain MRI findings: Cerebral atrophy (9/12 patients), non-specific white matter changes (8/12), intracranial calcification (2/12). In 8 cases, the brain abnormalities resolved.Some patients demonstrated stabilisation / recovery of neurological function in the absence of treatment, while in others the disease appeared to respond to immune suppression. Functional evidence: PMID: 10066179 Elchebly et al., 1999 - Ptpn1 knock-out (KO) mice are both viable and healthy, demonstrating enhanced insulin sensitivity and resistance to metabolic syndrome. PTPN1 is associated with {Insulin resistance, susceptibility to}, MIM:1258539 in OMIM. It is not associated with disease in ClinGen or Gene2Phenotype (resources accessed 24 Mar 2026). Probability of loss-of-function intolerance (pLI) score = 1.00 (predicted to be highly intolerant to LoF). Sources: Literature |
