Collection Method: clinical testing

The c.3645C>G (p.F1215L) alteration is located in exon 22 (coding exon 21) of the IGSF22 gene. This alteration results from a C to G substitution at nucleotide position 3645, causing the phenylalanine (F) at amino acid position 1215 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
