BabyScreen+ newborn screening v1.114 TERC Tommy Li Added phenotypes Dyskeratosis congenita for gene: TERC
BabyScreen+ newborn screening v0.1872 HMGCS2 Lilian Downie gene: HMGCS2 was added
gene: HMGCS2 was added to gNBS. Sources: Expert list
Mode of inheritance for gene: HMGCS2 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: HMGCS2 were set to PMID: 32259399, 32470406
Phenotypes for gene: HMGCS2 were set to HMG-CoA synthase-2 deficiency MIM#605911
Penetrance for gene: HMGCS2 were set to Incomplete
Review for gene: HMGCS2 was set to AMBER
Added comment: Metabolic disorder; patients present with hypoketotic hypoglycemia, encephalopathy, and hepatomegaly, usually precipitated by an intercurrent infection or prolonged fasting. Recover completely between illnesses, do develop fatty liver.
?incomplete penetrance or variable age of onset
On GUARDIAN and Rx Genes
Rx IV glucose during acute episodes, avoid prolonged fasting
Metabolic parameters are normal in between episodes, so no ability to do a confirmatory biochemical test.
Pros: readily treatable if child has an episode Cons: unncessary worry as child may never have episode
Super rare ?30 cases
Discuss with JC?

BabyScreen+ newborn screening v0.1862 HBB Zornitza Stark changed review comment from: Well established gene-disease associations.

Congenital onset.

Both sickle cell anaemia and beta thalassaemia are treatable disorders.

Beta thal: gene therapy (betibeglogene autotemcel - clinical trial), red cell transfusions, bone marrow transplantation (Hematopoietic Stem Cell Transplantation (HSCT)), Luspatercept

Sickle cell: glutamine, voxelotor, crizanlizumab, hydroxyurea, ,red cell transfusions, bone marrow transplantation (Hematopoietic Stem Cell Transplantation (HSCT)), gene therapy (BCH-BB694 BCL11A shmiR lentiviral vector - clinical trial and autologous CRISPR-Cas9-edited CD34+ hematopoietic stem and progenitor cells) - clinical trial)

Some of the beta-that variants are structural -- ability to detect reliably? For review.; to: Well established gene-disease associations.

We are only able to reliably screen for the HbS association.
