The c.250T>G (p.F84V) alteration is located in exon 3 (coding exon 2) of the TAF1D gene. This alteration results from a T to G substitution at nucleotide position 250, causing the phenylalanine (F) at amino acid position 84 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
