The c.439G>C (p.E147Q) alteration is located in exon 6 (coding exon 4) of the RAPGEFL1 gene. This alteration results from a G to C substitution at nucleotide position 439, causing the glutamic acid (E) at amino acid position 147 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
