The c.3848C>T (p.A1283V) alteration is located in exon 20 (coding exon 20) of the RGPD1 gene. This alteration results from a C to T substitution at nucleotide position 3848, causing the alanine (A) at amino acid position 1283 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
