Collection Method: clinical testing

The c.784G>A (p.A262T) alteration is located in exon 3 (coding exon 2) of the ZNF787 gene. This alteration results from a G to A substitution at nucleotide position 784, causing the alanine (A) at amino acid position 262 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
