The c.4048A>G (p.I1350V) alteration is located in exon 37 (coding exon 37) of the MROH2B gene. This alteration results from a A to G substitution at nucleotide position 4048, causing the isoleucine (I) at amino acid position 1350 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
