Collection Method: clinical testing

The c.503G>A (p.R168H) alteration is located in exon 6 (coding exon 6) of the RCSD1 gene. This alteration results from a G to A substitution at nucleotide position 503, causing the arginine (R) at amino acid position 168 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
