Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 22, 2024 | The c.2007A>T (p.E669D) alteration is located in exon 1 (coding exon 1) of the FSCB gene. This alteration results from a A to T substitution at nucleotide position 2007, causing the glutamic acid (E) at amino acid position 669 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
