The c.205T>G (p.F69V) alteration is located in exon 1 (coding exon 1) of the USP39 gene. This alteration results from a T to G substitution at nucleotide position 205, causing the phenylalanine (F) at amino acid position 69 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
