The c.169A>T (p.I57F) alteration is located in exon 2 (coding exon 1) of the CAPRIN1 gene. This alteration results from a A to T substitution at nucleotide position 169, causing the isoleucine (I) at amino acid position 57 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
