Article Synopsis
  • The study investigates the use of genomic DNA methylation analysis, or episignature profiling, in diagnosing neurodevelopmental disorders (NDDs) by evaluating two cohorts of patients: one with known pathogenic variants and another with uncertain mutations.
  • In the validation group of 59 patients, 90% exhibited expected episignatures, although some variants displayed overlapping profiles due to similar clinical symptoms.
  • In the test cohort of 38 patients, five cases identified novel pathogenic variants and confirmed diagnoses for conditions such as Cornelia de Lange syndrome, highlighting the potential of episignature analysis to tackle complex genetic diagnosis challenges.

The TRIO gene encodes a rho guanine exchange factor, the function of which is to exchange GDP to GTP, and hence to activate Rho GTPases, and has been described to impact neurodevelopment. Specific genotype-to-phenotype correlations have been established previously describing striking differentiating features seen in variants located in specific domains of the TRIO gene that are associated with opposite effects on RAC1 activity. Currently, 32 cases with a TRIO gene alteration have been published in the medical literature.

Neurodevelopmental disorders (NDDs) result from highly penetrant variation in hundreds of different genes, some of which have not yet been identified. Using the MatchMaker Exchange, we assembled a cohort of 27 individuals with rare, protein-altering variation in the transcriptional coregulator ZMYM3, located on the X chromosome. Most (n = 24) individuals were males, 17 of which have a maternally inherited variant; six individuals (4 male, 2 female) harbor de novo variants.

USP9X is an X-chromosome gene that escapes X-inactivation. Loss or compromised function of USP9X leads to neurodevelopmental disorders in males and females. While males are impacted primarily by hemizygous partial loss-of-function missense variants, in females de novo heterozygous complete loss-of-function mutations predominate, and give rise to the clinically recognisable USP9X-female syndrome.

Beyond network structure: How heterogeneous susceptibility modulates the spread of epidemics.

Sci Rep

The compartmental models used to study epidemic spreading often assume the same susceptibility for all individuals, and are therefore, agnostic about the effects that differences in susceptibility can have on epidemic spreading. Here we show that-for the SIS model-differential susceptibility can make networks more vulnerable to the spread of diseases when the correlation between a node's degree and susceptibility are positive, and less vulnerable when this correlation is negative. Moreover, we show that networks become more likely to contain a pocket of infection when individuals are more likely to connect with others that have similar susceptibility (the network is segregated).

Institute of Biology, Faculty of Natural Sciences and Mathematics, Sv. Kiril i Metodij University, Arhimedova 6, P.O.Box 162, Skopje, Republic of Macedonia.

Ghrelin is a 28-amino acid peptide hormone which modulates many physiological functions including cardiovascular homeostasis. Here we report some novel findings about the action of ghrelin on smooth muscle cells (SMC) freshly isolated from human mesenteric arteries. Ghrelin (10(-7) mol/l) significantly suppressed the iberiotoxin-blockable component of potassium currents (I(K)) and depolarized the cell membrane, while having no effect on Ca(2+) currents.

Adducts of bis(o-sulfobenzimidato)zinc(II) and mercury(II) with imidazole are synthesized for the first time and their mid-infrared vibrational spectra at ambient conditions and at 77 K are coupled with the earlier spectra-structural inferences to predict aspects of the respective solid-state structures. The spectrum of the H2O-matrix isolated OD fundamentals in the hydrated zinc compound is also investigated. The structure of the latter adduct contrasts the octahedral isostructural tetrad of mixed imidazole-saccharinates [M(H2O)2(C3H4N2)4](C7H4NO3S)2 [M = Mn(II), Fe(II), Co(II) and Ni(II)] in that it bears only a single crystallographic type of hydrogen bonded C2v water molecules and at least two structurally different o-sulfobenzimidate ligands, some of them likely utilized in a bridging fashion.

Effects of 5-R substitution (R = NO2, F, Cl, Br, I, CH3) and N-deprotonation on the 4000-400 cm(-1) region of the low temperature FT IR spectrum and the molecular structure of solid isatin are investigated. Harmonic IR spectra and molecular geometries of the 5-R isatins (except for Br and I analogues) are calculated at the HF/6-31G(d, p) level and compared with the experimental solid-state data. In general, substitution has small effect on the molecular structure and the IR spectrum of isatin.

Pathogenesis of anaemia in hyperparathyroidism.

Med Hypotheses

February 2000

Department of Nephrology, Medical Faculty, University "Sv Kiril i Metodij"-Skopje, Republic of Macedonia.

It is suggested that parathyroid hormone (PTH), when in excessive amounts, interferes with normal erythropoiesis by downregulating the erythropoietin receptors on erythroid progenitor cells in the bone marrow. Therefore, physiologic concentrations of EPO can no longer sustain normal red cell counts, so normocytic and normochromic anaemia ensues. In primary hyperparathyroidism (HPT), this effect is observed with very high concentrations of PTH.
