Existing evidence on the association of telomere length with life expectancy and the risk of various age related diseases is discordant. This inconsistency in the data may be due to methodological factors, e.g., the differences in the techniques for measuring telomere length, cell harvesting, DNA isolation, and material. One of the general requirements to experiments concerned with the measurement of telomere length is the high quality of DNA samples under study. The current review considers the most common errors during the measurement of telomere length associated with the improper quality of the biological material.

TERT de novo mutation-associated dyskeratosis congenita and porto-sinusoidal vascular disease: a case report.
J Med Case Rep

Background: Dyskeratosis congenita is a rare genetic disease due to telomere biology disorder and characterized by heterogeneous clinical manifestations and severe complications. "Porto-sinusoidal vascular disease" has been recently proposed, according to new diagnostic criteria, to replace the term "idiopathic non-cirrhotic portal hypertension." TERT plays an important role in telomeric DNA repair and replication.

Background: Telomere length (TL) is a marker of cellular health and aging. Physical exercise has been associated with longer telomeres and, therefore, healthier aging. However, results supporting such effects vary across studies.

Objective: Accelerated ageing indexed by telomere attrition is suggested in schizophrenia spectrum- (SCZ) and bipolar disorders (BD). While inflammation may promote telomere shortening, few studies have investigated the association between telomere length (TL) and markers of immune activation and inflammation in severe mental disorders.
Methods: Leucocyte TL defined as telomere template/amount of single-copy gene template (T/S ratio), was determined in participants with SCZ ( = 301) or BD ( = 211) and a healthy control group (HC, = 378).

Observational studies have suggested a link between leukocyte telomere length (LTL) and multiple sclerosis (MS) progression, but the causal relationship remains uncertain. This study investigates the causal association between LTL and MS progression using a bidirectional two-sample Mendelian randomization (MR) approach. We analyzed genome-wide association summary statistics data from 472,174 individuals for LTL and 12,584 MS patients for disease progression.

Donor cell leukemia (DCL), in which malignancy evolves from donor's stem cells, is an infrequent complication of allogeneic hematopoietic stem cell transplantation. Acute promyelocytic leukemia (APL) derived from donor cell is extremely rare and only four cases have been reported to date. Herein we report a case of donor cell-derived APL developing 32 months after haploidentical peripheral blood stem cell transplantation using posttransplant cyclophosphamide for myelodysplastic syndromes.
