Collection Method:clinical testing

The c.208A>G (p.I70V) alteration is located in exon 4 (coding exon 4) of the REEP3 gene. This alteration results from a A to G substitution at nucleotide position 208, causing the isoleucine (I) at amino acid position 70 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
