Collection Method: clinical testing

The c.977A>G (p.H326R) alteration is located in exon 7 (coding exon 7) of the MOGAT3 gene. This alteration results from a A to G substitution at nucleotide position 977, causing the histidine (H) at amino acid position 326 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
