The c.1016T>A (p.F339Y) alteration is located in exon 6 (coding exon 6) of the FNDC7 gene. This alteration results from a T to A substitution at nucleotide position 1016, causing the phenylalanine (F) at amino acid position 339 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
