The c.2106C>G (p.S702R) alteration is located in exon 7 (coding exon 6) of the PLEKHM3 gene. This alteration results from a C to G substitution at nucleotide position 2106, causing the serine (S) at amino acid position 702 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
