The c.5167C>T (p.L1723F) alteration is located in exon 22 (coding exon 22) of the RGPD2 gene. This alteration results from a C to T substitution at nucleotide position 5167, causing the leucine (L) at amino acid position 1723 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
