The c.826C>T (p.R276C) alteration is located in exon 5 (coding exon 5) of the TBPL2 gene. This alteration results from a C to T substitution at nucleotide position 826, causing the arginine (R) at amino acid position 276 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
