The c.1451G>A (p.R484K) alteration is located in exon 15 (coding exon 15) of the SHTN1 gene. This alteration results from a G to A substitution at nucleotide position 1451, causing the arginine (R) at amino acid position 484 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
