Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2023The c.1201C>T (p.R401W) alteration is located in exon 7 (coding exon 3) of the MGAT4C gene. This alteration results from a C to T substitution at nucleotide position 1201, causing the arginine (R) at amino acid position 401 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
