Mendeliome v1.436 TOMM7 Zornitza Stark edited their review of gene: TOMM7: Added comment: Second family reported in PMID 36282599: single affected individual with homozygous missense variant; clinical presentation with progeroid features but functional data supports underlying mitochondrial aetiology.

Maintain Amber rating as the two patients have quite disparate clinical presentations.; Changed publications: 36282599

Phenotypes for gene: TOMM7 were set to growth retardation, intellectual developmental disorder, hypotonia, and hepatopathy MONDO:0014911
Review for gene: TOMM7 was set to AMBER
Added comment: A single case identified with a homozygous variant in TOMM7 (c.73T>C, p.Trp25Arg) that presented with syndromic short stature, skeletal abnormalities, muscle hypotonia, microvesicular liver steatosis, and developmental delay. A mouse model of the missense variant demonstrated a bioenergetic defect and a phenotype of mitochondrial diseases. It also strongly suggested that the variant is hypomorphic because mice homozygous for this variant showed a milder phenotype than those with a homozygous Tomm7 deletion.

Added comment: TOM70 is a member of the TOM complex that transports cytosolic proteins into mitochondria.
Bi-allelic disease: one individual reported with compound heterozygous variants in TOMM70 [c.794C>T (p.T265M) and c.1745C>T (p.A582V)]. Clinical features included severe anaemia, lactic acidosis, and developmental delay. Some functional data: in vitro cell model compensatory experiments.
Monoallelic disease: de novo mono allelic variants in the C-terminal region of TOMM70 reported in two individuals. While both individuals exhibited shared symptoms including hypotonia, hyperreflexia, ataxia, dystonia, and significant white matter abnormalities, there were differences between the two individuals, most prominently the age of symptom onset, with one experiencing episodes of regression. Some functional data.
