Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 17, 2024 | The c.1285A>G (p.I429V) alteration is located in exon 12 (coding exon 11) of the MGAT4A gene. This alteration results from a A to G substitution at nucleotide position 1285, causing the isoleucine (I) at amino acid position 429 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
