Feb 06, 2024

The c.663C>G (p.F221L) alteration is located in exon 5 (coding exon 5) of the XKR5 gene. This alteration results from a C to G substitution at nucleotide position 663, causing the phenylalanine (F) at amino acid position 221 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
