Germline missense mutations affecting KRAS isoform B are associated with a severe noonan syndrome phenotype

Article Abstract:

Noonan syndrome (NS), a developmental disorder is characterized by short stature, facial dysmorphia, congenital heart disease, and multiple skeletal and hematology defects. The identification of heterozygous KRAS gene mutations in two subjects exhibiting a severe NS phenotype with features overlapping those of cardiofaciocutaneous and Costello syndromes is reported.

CEP290 mutations are frequently identified in the oculo-renal form of Joubert syndrome-related disorders

Article Abstract:

Comprehensive CEP290-mutation analysis is performed on nonoverlapping cohorts of Joubert syndrome-related disorder (JSRD)-affected patients with a proven molar tooth sign (MTS). The results have indicated that CEP290 mutations are frequently encountered and are largely specific to the JSRD-Senior-Loken syndrome (SLS) subtype.

Natural gene-expression variation in Down syndrome modulates the outcome of gene-dosage imbalance

Article Abstract:

A study providing the first extensive data set on HSA21 gene expression variation in Down syndrome is presented. Results underscore its role in modulating the outcome of gene- dosage imbalance.
