The c.587G>A (p.G196E) alteration is located in exon 6 (coding exon 5) of the SMCO2 gene. This alteration results from a G to A substitution at nucleotide position 587, causing the glycine (G) at amino acid position 196 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
