Zornitza Stark edited their review of gene: PNPT1: Added comment: Additional reports for association between mono allelic variants and SCA: PMID:39729134 (2024) reported an 11-year-old male of Indian descent with childhood-onset ataxia and severe sensorineural hearing loss. Genetic analysis identified heterozygous 3' splice site variant in the PNPT1 gene (c.2014-3 C > G). PMID:39899068 (2025) reported a 1-year-8-month-old female proband of Brazilian descent with Spinocerebellar Ataxia 25 that presented with progressive ataxia, cerebellar atrophy, and sensory neuropathy. She was identified with a novel heterozygous truncating variant in PNPT1 (c.2068del), which she inherited from her father. Although the father was previously reported as asymptomatic, he was affected with axonal and demyelinating polyneuropathy but not ataxia upon detailed examination. PMID:39924761 (2025) reported two unrelated families, where all individuals presented with sensory ataxic neuropathy (SAN), while some individuals developed cerebellar signs. Analysis of WGS variant data through the 100,000 Genomes Project identified two different heterozygous variants in these families. Family 1 underwent a 'quad' study and the previously reported c.2014‐3C>G variant segregated in all affected family members and was absent in all unaffected family members. Sanger sequencing confirmed segregation in two other individuals. c.2014‐3C>G is the same variant that was found in the 3-generation Australian family reported by PMID:35411967, where unaffected family members harboured the variant. A novel nonsense variant (c.2143C>T/ p.Arg715Ter) was found in both affected members of Family 2. PMID:40757543 (2024) reported an 18-year-old male presented with slowly progressive infancy-onset spasticity of the lower limbs and cerebellar ataxia, associated with painless strabismus, intellectual disability, urinary incontinence, bilateral progressive visual loss, and cognitive decline since early adolescence. The patient was identified with a heterozygous pathogenic variant c.162-1G>A in PNPT1 gene.; Changed rating: GREEN; Changed publications: 35411967, 39729134, 39899068, 39924761, 40757543 |

| Mendeliome v1.114 | PNPT1 | Zornitza Stark edited their review of gene: PNPT1: Added comment: Three families reported with heterozygous variants and SCA25. Incomplete penetrance in one of the families. In the third family, the variant was inherited from an asymptomatic 80+ year old. Note bi-allelic variants in this gene cause a mitochondrial disorder. Exact mechanism through which mono-allelic variants cause SCA25 not elucidated: authors speculate abnormal accumulation of mitochondrial RNA with subsequent leakage into the cytosol that may trigger a type 1 interferon response leading to neuroinflammation with neuronal dysfunction or neuronal loss.; Changed rating: AMBER; Changed publications: 35411967; Changed phenotypes: Spinocerebellar ataxia 25, MIM# 608703; Changed mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
