DNA-pools targeted-sequencing as a robust cost-effective method to detect rare variants: Application to dilated cardiomyopathy genetic diagnosis
Clin Genet. 2023 Oct 30. doi: 10.1111/cge.14427. Online ahead of print.ABSTRACTDilated cardiomyopathy (DCM) is a heart disease characterized by left ventricular dilatation and systolic dysfunction. In 30% of cases, pathogenic variants, essentially private to each patient, are identified in at least one of almost 50 reported genes. Thus, while costly, exons capture-based Next Generation Sequencing (NGS) of a targeted gene panel appears as the best strategy to genetically diagnose DCM. Here, we report a NGS strategy applied to pools of 8 DNAs from DCM patients and validate its robustness for rare variants detection at 4-fold...

Genetic and phenotypic findings in 34 novel Spanish patients with DDX3X neurodevelopmental disorder
This article describes 34 additional patients to those already reported, contributing with 25 novel variants and a deep phenotypic characterization. A clinical review of our cohort of DDX3X-NDD patients is performed comparing them to those previously published.PMID:37904618 | DOI:10.1111/cge.14440 (Source: Clinical Genetics)

De novo enhancer deletion of LMX1B produces a mild nail-patella clinical phenotype
In this study, we present a family with four affected individuals across two generations with a deletion spanning a conserved upstream LMX1B-binding sequence. This deletion is de novo in the mother of three affected children. Furthermore, in this family, the manifestations appear limited to the nails and limbs, and therefore may reflect an attenuated phenotype of the classic Nail-Patella phenotype that includes ophthalmological and renal manifestations.PMID:37899549 | DOI:10.1111/cge.14447 (Source: Clinical Genetics)

Rigorous evaluation of genetic and epigenetic effects on clinical laboratory measurements using Japanese monozygotic twins
Clin Genet. 2023 Oct 29. doi: 10.1111/cge.14443. Online ahead of print.ABSTRACTThe investigation of environmental effects on clinical measurements using individual samples is challenging because their genetic and environmental factors are different. However, using monozygotic twins (MZ) makes it possible to investigate the influence of environmental factors as they have the same genetic factors within pairs because the difference in the clinical traits within the MZ mostly reflect the influence of environmental factors. We hypothesized that the within-pair differences in the traits that are strongly affected by genetic fac...
