The c.1487G>A (p.R496K) alteration is located in exon 7 (coding exon 7) of the KLHL1 gene. This alteration results from a G to A substitution at nucleotide position 1487, causing the arginine (R) at amino acid position 496 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
