The c.785G>C (p.R262T) alteration is located in exon 9 (coding exon 8) of the TOMM40L gene. This alteration results from a G to C substitution at nucleotide position 785, causing the arginine (R) at amino acid position 262 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
