The c.3946G>A (p.E1316K) alteration is located in exon 23 (coding exon 22) of the IGSF22 gene. This alteration results from a G to A substitution at nucleotide position 3946, causing the glutamic acid (E) at amino acid position 1316 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
