Collection Method: clinical testing

The c.1705C>T (p.R569C) alteration is located in exon 16 (coding exon 16) of the BRD9 gene. This alteration results from a C to T substitution at nucleotide position 1705, causing the arginine (R) at amino acid position 569 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
