not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 27, 2023 | The c.2678C>A (p.A893D) alteration is located in exon 19 (coding exon 18) of the SEMA6A gene. This alteration results from a C to A substitution at nucleotide position 2678, causing the alanine (A) at amino acid position 893 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
