Collection Method: clinical testing

The c.899C>T (p.A300V) alteration is located in exon 8 (coding exon 8) of the ANKMY2 gene. This alteration results from a C to T substitution at nucleotide position 899, causing the alanine (A) at amino acid position 300 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
