Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 15, 2021 | The c.4393G>A (p.D1465N) alteration is located in exon 25 (coding exon 24) of the SCN7A gene. This alteration results from a G to A substitution at nucleotide position 4393, causing the aspartic acid (D) at amino acid position 1465 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
