The c.695C>G (p.T232S) alteration is located in exon 7 (coding exon 7) of the REEP3 gene. This alteration results from a C to G substitution at nucleotide position 695, causing the threonine (T) at amino acid position 232 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
