The c.1166G>A (p.R389H) alteration is located in exon 11 (coding exon 8) of the SCMH1 gene. This alteration results from a G to A substitution at nucleotide position 1166, causing the arginine (R) at amino acid position 389 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
