Genes affected

TOMM22 (HGNC:18002): (translocase of outer mitochondrial membrane 22) The protein encoded by this gene is an integral membrane protein of the mitochondrial outer membrane. The encoded protein interacts with TOMM20 and TOMM40, and forms a complex with several other proteins to import cytosolic preproteins into the mitochondrion. [provided by RefSeq, Jul 2008]

Nov 21, 2022

The c.29C>T (p.A10V) alteration is located in exon 1 (coding exon 1) of the TOMM22 gene. This alteration results from a C to T substitution at nucleotide position 29, causing the alanine (A) at amino acid position 10 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
