Panel Version: 6.3

Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal

Green List (high evidence)

Comment on list classification: TEFM has already been promoted to green rating on Mitochondrial disorders panel (https://panelapp.genomicsengland.co.uk/panels/112/gene/TEFM/) as detailed in the below reviews copied from that panel.

As there is sufficient evidence available for the gene-disease association, this gene can be promoted to green rating on this panel in the next GMS update.

PMID: 36823193 (2023) report seven TEFM variants (four missense, two frameshift and one in-frame 2-amino acid deletion) in seven individuals from five unrelated families who present with mitochondrial respiratory chain deficiency and a wide range of infantile or childhood-onset neurological and neuromuscular symptoms, due to abnormal mitochondrial transcription.
