Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.446G>A (p.R149H) alteration is located in exon 7 (coding exon 3) of the MGAT4C gene. This alteration results from a G to A substitution at nucleotide position 446, causing the arginine (R) at amino acid position 149 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
