The c.749A>G (p.H250R) alteration is located in exon 4 (coding exon 4) of the MANEAL gene. This alteration results from a A to G substitution at nucleotide position 749, causing the histidine (H) at amino acid position 250 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
