The c.243G>C (p.Q81H) alteration is located in exon 2 (coding exon 1) of the SMCO3 gene. This alteration results from a G to C substitution at nucleotide position 243, causing the glutamine (Q) at amino acid position 81 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
