The c.35G>A (p.R12H) alteration is located in exon 4 (coding exon 1) of the KSR1 gene. This alteration results from a G to A substitution at nucleotide position 35, causing the arginine (R) at amino acid position 12 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
