The c.737A>G (p.K246R) 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 737, causing the lysine (K) at amino acid position 246 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
