Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 11, 2021 | The c.2462C>T (p.T821M) alteration is located in exon 19 (coding exon 18) of the SEMA6A gene. This alteration results from a C to T substitution at nucleotide position 2462, causing the threonine (T) at amino acid position 821 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
