The c.1955A>G (p.H652R) alteration is located in exon 12 (coding exon 12) of the LEO1 gene. This alteration results from a A to G substitution at nucleotide position 1955, causing the histidine (H) at amino acid position 652 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
