Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 26, 2022 | The c.1133A>T (p.K378I) alteration is located in exon 3 (coding exon 3) of the TMTC2 gene. This alteration results from a A to T substitution at nucleotide position 1133, causing the lysine (K) at amino acid position 378 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
