The c.830T>C (p.V277A) alteration is located in exon 5 (coding exon 5) of the TBPL2 gene. This alteration results from a T to C substitution at nucleotide position 830, causing the valine (V) at amino acid position 277 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
