The c.6326C>T (p.S2109F) alteration is located in exon 7 (coding exon 5) of the USF3 gene. This alteration results from a C to T substitution at nucleotide position 6326, causing the serine (S) at amino acid position 2109 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
