The c.702C>G (p.D234E) alteration is located in exon 3 (coding exon 2) of the RBM6 gene. This alteration results from a C to G substitution at nucleotide position 702, causing the aspartic acid (D) at amino acid position 234 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
