Drosophila models of phosphatidylinositol glycan biosynthesis class A congenital disorder of glycosylation (PIGA-CDG) mirror patient phenotypes.

Mutations in the phosphatidylinositol glycan biosynthesis class A (PIGA) gene cause a rare, X-linked recessive congenital disorder of glycosylation. Phosphatidylinositol glycan biosynthesis class A congenital disorder of glycosylation (PIGA-CDG) is characterized by seizures, intellectual and developmental delay, and congenital malformations. The PIGA gene encodes an enzyme involved in the first step of glycosylphosphatidylinositol (GPI) anchor biosynthesis.

DIS3 Variants are Associated With Primary Ovarian Insufficiency: Importance of Transcription/Translation in Oogenesis.

Context: A genetic etiology accounts for the majority of unexplained primary ovarian insufficiency (POI).

Objective: We hypothesized a genetic cause of POI for a sister pair with primary amenorrhea.

Design: The study was an observational study.

Importation of plasma and use of apheresis platelets as risk reduction measures for variant Creutzfeldt-Jakob disease: The SaBTO review.

Following recognition that blood, blood components, tissues and organs donated by infected donors could transmit infectious prions causing variant Creutzfeldt-Jakob Disease (vCJD), several risk reduction measures were introduced in the UK. The Advisory Committee on the Safety of Blood, Tissues and Organs (SaBTO) established a working group to review the measures in place. Factors considered included: ethical issues around the current provisions and potential changes; operational issues for blood establishments and hospitals; a review from the Advisory Committee on Dangerous Pathogens (ACDP) showing the downward trend in the estimated number of future cases of vCJD; and cost-effectiveness.

Causal and Candidate Gene Variants in a Large Cohort of Women With Primary Ovarian Insufficiency.

Context: A genetic etiology likely accounts for the majority of unexplained primary ovarian insufficiency (POI).

Objective: We hypothesized that heterozygous rare variants and variants in enhanced categories are associated with POI.

Design: The study was an observational study.

A screen identifies NKCC1 as a modifier of NGLY1 deficiency.

N-Glycanase 1 (NGLY1) is a cytoplasmic deglycosylating enzyme. Loss-of-function mutations in the gene cause NGLY1 deficiency, which is characterized by developmental delay, seizures, and a lack of sweat and tears. To model the phenotypic variability observed among patients, we crossed a model of NGLY1 deficiency onto a panel of genetically diverse strains.
