The c.608G>A (p.R203H) alteration is located in exon 6 (coding exon 6) of the NSRP1 gene. This alteration results from a G to A substitution at nucleotide position 608, causing the arginine (R) at amino acid position 203 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
