The c.740G>A (p.S247N) alteration is located in exon 6 (coding exon 6) of the SRSF4 gene. This alteration results from a G to A substitution at nucleotide position 740, causing the serine (S) at amino acid position 247 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
