Collection Method: clinical testing

The c.1016C>T (p.S339F) alteration is located in exon 8 (coding exon 7) of the ARFIP2 gene. This alteration results from a C to T substitution at nucleotide position 1016, causing the serine (S) at amino acid position 339 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
