The c.22C>G (p.L8V) alteration is located in exon 1 (coding exon 1) of the RBM48 gene. This alteration results from a C to G substitution at nucleotide position 22, causing the leucine (L) at amino acid position 8 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
