The c.5098C>G (p.Q1700E) alteration is located in exon 22 (coding exon 22) of the RGPD8 gene. This alteration results from a C to G substitution at nucleotide position 5098, causing the glutamine (Q) at amino acid position 1700 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
