The c.518G>A (p.R173H) alteration is located in exon 4 (coding exon 3) of the SCARA5 gene. This alteration results from a G to A substitution at nucleotide position 518, causing the arginine (R) at amino acid position 173 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
