Apr 27, 2023

The c.163T>C (p.F55L) alteration is located in exon 3 (coding exon 3) of the RAP1GDS1 gene. This alteration results from a T to C substitution at nucleotide position 163, causing the phenylalanine (F) at amino acid position 55 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
