Collection Method: clinical testing

The c.970G>C (p.E324Q) alteration is located in exon 7 (coding exon 7) of the MOGAT3 gene. This alteration results from a G to C substitution at nucleotide position 970, causing the glutamic acid (E) at amino acid position 324 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
