Collection Method: clinical testing

The c.269G>A (p.G90D) alteration is located in exon 4 (coding exon 1) of the ANKRD34A gene. This alteration results from a G to A substitution at nucleotide position 269, causing the glycine (G) at amino acid position 90 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
