Genes affected
TIMM22 (HGNC:17317): (translocase of inner mitochondrial membrane 22) Multipass transmembrane proteins are brought into mitochondria and inserted into the mitochondrial inner membrane by way of the TIM22 complex. This complex has six subunits and is a twin-pore translocase. The protein encoded by this gene is a subunit of TIM22 and represents the voltage-activated and signal-gated channel.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.32C>T (p.S11L) alteration is located in exon 1 (coding exon 1) of the TIMM22 gene. This alteration results from a C to T substitution at nucleotide position 32, causing the serine (S) at amino acid position 11 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
