|Our family at Duke University - happy with the study results!|
On May 3, 2012, after four long years of searching, Bertrand finally received a diagnosis!
|The result. We could undertake PGD IVF if desired.|
Using next generation sequencing, the fabulous researchers at Duke University discovered that Bertrand inherited 2 distinct mutations in the NGLY1 gene: a frameshift in exon 12 from me and a nonsense mutation in exon 8 from Matthew. NGLY1 encodes N-glycanase 1, which is the enzyme involved with the degradation of misfolded N-linked glycoproteins.
|Bertrand, Cristina, Matthew and control NGLY1 expression.|
Bertrand is the first documented case of an NGLY1 disorder. Efforts are currently underway to confirm a second case of N-glycanase deficiency and establish causality. You read that right: within 2 weeks we may know for certain if another child has the same kind of disorder as Bertrand! And, after that, other similar but undiagnosed children may be tested for errors in NGLY1 as well.
We finally have an answer.
Something to write in on forms. Something to easily say when people ask about Bertrand.
And, as more NGLY1 children are found, we will no longer be alone.
