Introduction: Heterozygous pathogenic variants in NTRK2 (HGNC: 8032) have been associated with global developmental delay. However, only scattered cases have been described in small or general studies. The aim of our work was to consolidate our understanding of NTRK2-related disorders and to delineate the clinical presentation METHODS: We report extended cohort of 44 affected individuals, of whom 19 are from the literature and 25 were previously unreported.

Design: Retrospective observational study performed between 2020 and 2022.
Setting: Clinic.
Background: Shortened telomere length (TL) is a genomic risk factor for fibrotic interstitial lung disease (ILD), but its role in clinical management is unknown.
Research Question: What is the clinical impact of TL testing on the management of ILD?
Study Design And Methods: Patients were evaluated in the Columbia University ILD clinic and underwent Clinical Laboratory Improvement Amendments-certified TL testing by flow cytometry and fluorescence in situ hybridization (FlowFISH) as part of clinical treatment. Short TL was defined as below the 10th age-adjusted percentile for either granulocytes or lymphocytes by FlowFISH.
