Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 18, 2023 | The c.908A>C (p.N303T) alteration is located in exon 6 (coding exon 6) of the TNRC6A gene. This alteration results from a A to C substitution at nucleotide position 908, causing the asparagine (N) at amino acid position 303 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
