The impact of alpha-1 antitrypsin deficiency alleles on lung cancer survival.

Different studies have shown that carrying an alpha-1 antitrypsin (AAT) deficiency allele is an independent risk factor for developing lung cancer (LC). However, to date, little is known regarding whether carrying a deficiency allele may be a prognostic factor in the evolution of LC. A prospective observational study was carried out which consecutively included patients diagnosed with LC in University Hospital "Nuestra Señora de Candelaria" between December 2017 and August 2020.

Evaluation of a whole-exome sequencing pipeline and benchmarking of causal germline variant prioritizers.

Most causal variants of Mendelian diseases are exonic. Whole-exome sequencing (WES) has become the diagnostic gold standard, but causative variant prioritization constitutes a bottleneck. Here we assessed an in-house sample-to-sequence pipeline and benchmarked free prioritization tools for germline causal variants from WES data.

Clinical and molecular diagnosis of non-phosphomannomutase 2 N-linked congenital disorders of glycosylation in Spain.

The congenital disorders of glycosylation (CDG) are defects in glycoprotein and glycolipid glycan synthesis and attachment. They affect multiple organ/systems, but non-specific symptoms render the diagnosis of the different CDG very challenging. Phosphomannomutase 2 (PMM2)-CDG is the most common CDG, but advances in genetic analysis have shown others to occur more commonly than previously thought.

Effectiveness of a screening protocol for gestational diabetes in pregnant Spanish women.

Objective: Screening for gestational diabetes mellitus (GDM) and its treatment can reduce health risks for the mother and child. This study estimated the prevalence of undetected GDM in Tenerife Island, to determine the rate of dropout from the diagnostic protocol and to identify the features of the protocol that reduced its effectiveness.

Methods: We calculated GDM prevalence and the breaches of the diagnostic protocol out of 12,084 pregnant women who started the GDM detection program during 2004-2006.
