Nov 15, 2024

The c.839A>T (p.D280V) alteration is located in exon 6 (coding exon 6) of the STARD7 gene. This alteration results from a A to T substitution at nucleotide position 839, causing the aspartic acid (D) at amino acid position 280 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
