MST1 mutations in autosomal recessive primary immunodeficiency characterized by defective naive T-cell survival.

The molecular mechanisms that underlie T-cell quiescence are poorly understood. In the present study, we report a primary immunodeficiency phenotype associated with MST1 deficiency and primarily characterized by a progressive loss of naive T cells. The in vivo consequences include recurrent bacterial and viral infections and autoimmune manifestations. MST1-deficient T cells poorly expressed the...

Mutations in HPCA cause autosomal-recessive primary isolated dystonia.

Reports of primary isolated dystonia inherited in an autosomal-recessive (AR) manner, often lumped together as "DYT2 dystonia," have appeared in the scientific literature for several decades, but no genetic cause has been identified to date. Using a combination of homozygosity mapping and whole-exome sequencing in a consanguineous kindred affected by AR isolated dystonia, we identified homozygo...

VSX2 mutations in autosomal recessive microphthalmia

PURPOSE To further explore the spectrum of mutations in the Visual System Homeobox 2 (VSX2/CHX10) gene previously found to be associated with autosomal recessive microphthalmia. METHODS We screened 95 probands with syndromic or isolated developmental ocular conditions (including 55 with anophthalmia/microphthalmia) for mutations in VSX2. RESULTS Homozygous mutations in VSX2 were identified ...

A primary immunodeficiency characterized by defective immunoglobulin class switch recombination and impaired DNA repair

Immunoglobulin class switch recombination (CSR) deficiencies are rare primary immunodeficiencies, characterized by a lack of switched isotype (IgG, IgA, or IgE) production, variably associated with abnormal somatic hypermutation (SHM). Deficiencies in CD40 ligand, CD40, activation-induced cytidine deaminase, and uracil-N-glycosylase may account for this syndrome. We previously described another...

Nephrocalcinosis (Enamel Renal Syndrome) Caused by Autosomal Recessive FAM20A Mutations

BACKGROUND/AIMS Calcium homeostasis requires regulated cellular and interstitial systems interacting to modulate the activity and movement of this ion. Disruption of these systems in the kidney results in nephrocalcinosis and nephrolithiasis, important medical problems whose pathogenesis is incompletely understood. METHODS We investigated 25 patients from 16 families with unexplained nephroca...
