The c.590A>G (p.H197R) alteration is located in exon 5 (coding exon 4) of the LMNTD1 gene. This alteration results from a A to G substitution at nucleotide position 590, causing the histidine (H) at amino acid position 197 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
