Collection Method: clinical testing

The c.220T>A (p.F74I) alteration is located in exon 3 (coding exon 3) of the CILP2 gene. This alteration results from a T to A substitution at nucleotide position 220, causing the phenylalanine (F) at amino acid position 74 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
