Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.127G>A (p.G43R) alteration is located in exon 2 (coding exon 2) of the TOMM7 gene. This alteration results from a G to A substitution at nucleotide position 127, causing the glycine (G) at amino acid position 43 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
