Four Swedish families in northern Sweden with polycystic lipomembranous osteodysplasia (PLO-SL) were studied genealogically. Historical and genealogical date provided evidence for a Finnish origin. Both parents of two of the families could be traced back to Finnish ancestors, and the other two families had a common origin in a region with a known Finnish influence, but without evidence for Finnish ancestry. PLO-SL is the first rare monogenic disease with an autosomal recessive inheritance in Sweden with a probable Finnish origin.

Article Synopsis
  • The study examines the role of mutations in the TREM2 gene, previously linked to Nasu-Hakola disease, in three unrelated patients diagnosed with the behavioral variant of frontotemporal dementia (bvFTD).
  • Each patient was evaluated through various neurological, psychiatric, and cognitive assessments, revealing a correlation between specific TREM2 variants and bvFTD symptoms.
  • Although the patients showed some clinical similarities to Nasu-Hakola disease, they exhibited distinct characteristics, including differences in age of onset, neuroimaging results, and disease progression.

Article Synopsis
  • TREM2 is a protein that plays a key role in immune responses and neuroinflammation, with mutations linked to neurodegenerative diseases, particularly Nasu-hakola disease (NHD) that leads to bone lesions and early dementia.
  • Whole-exome sequencing was performed on a family of three siblings suspected to have NHD, revealing a new genetic deletion in the TREM2 gene that correlates with their condition.
  • The study enhances understanding of TREM2's role in various diseases, contributing to better diagnoses and potential therapies for affected individuals.

Context: The specialised family of triggering receptors expressed on myeloid cells (TREMs) plays a pivotal role in causing neurodegenerative disorders and activating microglial anti-inflammatory responses. Nasu-Hakola disease (NHD), a rare autosomal recessive disorder, has been associated with mutations in TREM2, which is also responsible for raising the risk of Alzheimer's disease (AD). Herein, we have made an endeavour to differentiate the confirmed pathogenic variants in TREM2 extra-cellular domain (ECD) linked with NHD and AD using mutation-induced fold stability change (∆∆G), with the computation of 12distinct structure-based methods through saturation mutagenesis.

TREM2 is an innate immune receptor expressed by microglia in the adult brain. Genetic variation in the TREM2 gene has been implicated in risk for Alzheimer's disease and frontotemporal dementia, while homozygous TREM2 mutations cause a rare leukodystrophy, Nasu-Hakola disease (NHD). Despite extensive investigation, the role of TREM2 in NHD pathogenesis remains poorly understood.
