Collection Method: clinical testing

The c.1981A>G (p.K661E) alteration is located in exon 7 (coding exon 7) of the AGAP4 gene. This alteration results from a A to G substitution at nucleotide position 1981, causing the lysine (K) at amino acid position 661 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
