The c.1186A>G (p.K396E) alteration is located in exon 6 (coding exon 6) of the SRSF4 gene. This alteration results from a A to G substitution at nucleotide position 1186, causing the lysine (K) at amino acid position 396 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
