Collection Method: clinical testing

The c.923A>C (p.E308A) alteration is located in exon 9 (coding exon 9) of the ZNF277 gene. This alteration results from a A to C substitution at nucleotide position 923, causing the glutamic acid (E) at amino acid position 308 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
