The c.739A>G (p.T247A) alteration is located in exon 2 (coding exon 2) of the THSD7B gene. This alteration results from a A to G substitution at nucleotide position 739, causing the threonine (T) at amino acid position 247 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
