The c.487T>C (p.Y163H) alteration is located in exon 4 (coding exon 3) of the TAF1D gene. This alteration results from a T to C substitution at nucleotide position 487, causing the tyrosine (Y) at amino acid position 163 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
