Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.206A>G (p.E69G) alteration is located in exon 3 (coding exon 3) of the STARD9 gene. This alteration results from a A to G substitution at nucleotide position 206, causing the glutamic acid (E) at amino acid position 69 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
