Collection Method: clinical testing

The c.2161G>A (p.E721K) alteration is located in exon 17 (coding exon 17) of the AFAP1L2 gene. This alteration results from a G to A substitution at nucleotide position 2161, causing the glutamic acid (E) at amino acid position 721 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
