Collection Method: clinical testing

The c.791A>T (p.E264V) alteration is located in exon 9 (coding exon 9) of the ANKRD29 gene. This alteration results from a A to T substitution at nucleotide position 791, causing the glutamic acid (E) at amino acid position 264 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
