Condition	Inheritance	Intervention Categories	Intervention/Rationale	Manifestation Categories	References
Myoclonic epilepsy with ragged red fibers; Nephropathy, tubulointerstitial; Encephalopathy, mitochondrial; Epilepsy, mitochondrial; Myopathy, mitochondrial; Mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes	Maternal	General	Genetic knowledge may be beneficial related to issues such as selection of optimal supportive care, informed medical decision-making, prognostic considerations, and avoidance of unnecessary testing	Audiologic/Otolaryngologic; Biochemical; Musculoskeletal; Neurologic; Renal	15184630
Mitochondrial variants may involve a variety of sequelae, including hearing impairment; As with other forms of epilepsy, optimal seizure control is advantageous, and genetic diagnosis may aid with medication selection

ClinVar

This is a list of variants' phenotypes submitted to ClinVar and linked to the MT-TF gene.

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the MT-TF gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.
