Collection Method:clinical testing

The c.1180G>A (p.E394K) alteration is located in exon 4 (coding exon 3) of the ANKAR gene. This alteration results from a G to A substitution at nucleotide position 1180, causing the glutamic acid (E) at amino acid position 394 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
