Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 28, 2023 | The c.2019A>T (p.K673N) alteration is located in exon 16 (coding exon 16) of the CASC1 gene. This alteration results from a A to T substitution at nucleotide position 2019, causing the lysine (K) at amino acid position 673 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
