Genes affected

TOMM40 (HGNC:18001): (translocase of outer mitochondrial membrane 40) The protein encoded by this gene is localized in the outer membrane of the mitochondria. It is the channel-forming subunit of the translocase of the mitochondrial outer membrane (TOM) complex that is essential for import of protein precursors into mitochondria. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Aug 2015]

Collection Method: clinical testing

The c.607G>A (p.V203I) alteration is located in exon 6 (coding exon 5) of the TOMM40 gene. This alteration results from a G to A substitution at nucleotide position 607, causing the valine (V) at amino acid position 203 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
