The c.2237A>G (p.K746R) alteration is located in exon 17 (coding exon 17) of the AFAP1L2 gene. This alteration results from a A to G substitution at nucleotide position 2237, causing the lysine (K) at amino acid position 746 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
