The c.829T>C (p.W277R) alteration is located in exon 6 (coding exon 5) of the BLZF1 gene. This alteration results from a T to C substitution at nucleotide position 829, causing the tryptophan (W) at amino acid position 277 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
