Collection Method: clinical testing

The c.580G>T (p.A194S) alteration is located in exon 5 (coding exon 5) of the MOGAT3 gene. This alteration results from a G to T substitution at nucleotide position 580, causing the alanine (A) at amino acid position 194 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
