The c.188G>A (p.R63K) alteration is located in exon 1 (coding exon 1) of the LVRN gene. This alteration results from a G to A substitution at nucleotide position 188, causing the arginine (R) at amino acid position 63 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
