Mitochondrial disorders v9.15 TOMM7 Achchuthan Shanmugasundram edited their review of gene: TOMM7: Changed rating: GREEN; Changed mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Mitochondrial disorders v9.14 TOMM7 Achchuthan Shanmugasundram Classified gene: TOMM7 as Amber List (moderate evidence)
Mitochondrial disorders v9.14 TOMM7 Achchuthan Shanmugasundram Added comment: Comment on list classification: As there are three unrelated cases reported with biallelic TOMM7 variants and this gene has already been recommended for green rating on R63 Possible mitochondrial disorder - nuclear genes (https://panelapp.genomicsengland.co.uk/panels/539/gene/TOMM7/) panel, this gene is being recommended for promotion to green rating on this panel too.

PMID: 31907385 - Wei et al 2020 - report a patient with severe anemia, lactic acidosis, and developmental delay in which two compound heterozygous variants in TOMM70 [c.794C>T (p.T265M) and c.1745C>T (p.A582V)] were identified. Functional studies showed that patient-derived cells exhibited multi-oxidative phosphorylation system (OXPHOS) complex defects. Abstract only accessed.

PMID: 32356556 - Dutta et al 2020 - report 2 patients with de novo heterozygous missense variants in the C-terminal region of TOMM70. Both patients had shared symptoms including hypotonia, hyper-reflexia, ataxia, dystonia and significant white matter abnormalities. Patient 1 showed severe global developmental delay. However, for patient 1 a neurodevelopmental disorder was noted in infancy, but patient 2 developed as normal until age 4 when neurological regression occurred. Some functional data from Drosophila show that the variants cause partial loss of function.

3 cases but different mode of inheritance and phenotypic presentation.
