One of the significant unanswered questions about COVID-19 epidemiology relates to the role of children in transmission. This study uses data on infections within households in order to estimate the susceptibility and infectivity of children compared to those of adults. The data were collected from households in the city of Bnei Brak, Israel, in which all household members were tested for COVID-19 using PCR (637 households, average household size of 5.

The aims of our research were to define the genotype-phenotype correlations of mutations in the phenylalanine hydroxylase (PAH) gene that cause phenylketonuria (PKU) among the Israeli population. The mutation spectrum of the PAH gene in PKU patients in Israel is described, along with a discussion on genotype-phenotype correlations. By using polymerase chain reaction/denaturing high-performance liquid chromatography (PCR/dHPLC) and DNA sequencing, we screened all exons of the PAH gene in 180 unrelated patients with four different PKU phenotypes [classic PKU, moderate PKU, mild PKU, and mild hyperphenylalaninemia (MHP)].

Carbonic anhydrase II (CA2) deficiency syndrome is an autosomal recessive disorder leading to osteopetrosis, renal tubular acidosis, and cerebral calcifications. Affected members of an Arab family with the CA2 deficiency syndrome carried the "Egyptian mutation" in CA2, i.e.

In the present study we analyzed changes in the pattern of gene expression in endothelial cells (HUVEC) exposed to elevated homocysteine levels under flow conditions. RNA samples of untreated and homocysteine treated EC were analyzed using a human cDNA array containing 588 cDNAs relevant to the cardiovascular system. Exposure to homocysteine under flow resulted in altered expression of 8 genes, the alterations of 3 of which were further confirmed by RT-PCR analysis: upregulation of MCP-1 and of profilin-I, and downregulation of alpha-catenin.
