Sarah Leigh changed review comment from: LETM1 variants have been associated with Neurodegeneration, childhood-onset, with multisystem involvement due to mitochondrial dysfunction, OMIM:620089 and as moderate Gen2Phen gene for LETM1-related neurodevelopmental disorder. PMID: 36055214 reports 10 LETM1 variants in 18 patients from 11 unrelated families with childhood-onset neurodegeneration with multisystem involvement, many of whom were gathered using the GeneMatcher Program. The most common clinical features of this cohort, where an assessment could be made, were: mitochondrial respiratory complex deficiencies 11/11 (100%), global developmental delay / intellectual disability 17/18 (94%), bilateral sensorineural hearing loss 11/14 (78%) , impaired vision 10/10 (100%), cerebellar ataxia 7/9 (78%), seizures 10/15 (67%), hypotonia 11/18 (61%) (PMID: 36055214, figure 1c).; to: LETM1 variants have been associated with Neurodegeneration, childhood-onset, with multisystem involvement due to mitochondrial dysfunction, OMIM:620089 and as moderate Gen2Phen gene for LETM1-related neurodevelopmental disorder.
