Collection Method:clinical testing

The c.347A>G (p.D116G) alteration is located in exon 5 (coding exon 2) of the BBX gene. This alteration results from a A to G substitution at nucleotide position 347, causing the aspartic acid (D) at amino acid position 116 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
