Collection Method: clinical testing

The c.115T>C (p.F39L) alteration is located in exon 2 (coding exon 1) of the FAM26F gene. This alteration results from a T to C substitution at nucleotide position 115, causing the phenylalanine (F) at amino acid position 39 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
