The SORL1 protein plays a protective role against the secretion of the amyloid β peptide, a key event in the pathogeny of Alzheimer's disease. We assessed the impact of SORL1 rare variants in early-onset Alzheimer's disease (EOAD) in a case-control setting. We conducted a whole exome analysis among 484 French EOAD patients and 498 ethnically matched controls. After collapsing rare variants (minor allele frequency ≤1%), we detected an enrichment of disruptive and predicted damaging missense SORL1 variants in cases (odds radio (OR)=5.03, 95% confidence interval (CI)=(2.02-14.99), P=7.49.10(-5)). This enrichment was even stronger when restricting the analysis to the 205 cases with a positive family history (OR=8.86, 95% CI=(3.35-27.31), P=3.82.10(-7)). We conclude that predicted damaging rare SORL1 variants are a strong risk factor for EOAD and that the association signal is mainly driven by cases with positive family history.

A 29-year-old Spanish Caucasian man, without relevant family history, was attended in our unit due to an undiagnosed skeletal dysplasia associated with low bone mass and several fragility fractures throughout his childhood and adolescence. DXA exams throughout his life showed very low BMD values; currently, his spinal and femoral neck T-scores were - 4.3 and - 3.

Unlabelled: Nucleic acid amplification tests (NAATs) are the method of choice for diagnosis, but these strategies are susceptible to target site mutations. variants escaping detection with the Aptima Combo 2 (AC2) assay on the Hologic Panther instrument from 23S rRNA mutations have been reported in Nordic countries, England, Japan, and the United States. Given the potential for false negative results, this study investigated whether strains of with AC2 target site mutations were present in Canada.

T-cell prolymphocytic leukemia (T-PLL) is a rare mature T-cell lymphoma that is usually associated with poor prognosis and short overall survival. We present a case of a 61-year-old woman presenting with T-PLL and the leukemic cells harboring (-breakpoint cluster region; -ABL protooncogene 1) fusion transcripts as the result of a variant of t(9;22)(q34;q11) called Philadelphia translocation: t(9;22;18)(q34;q11;q21). Sequencing revealed a rare transcript with an exon 6 breakpoint corresponding to e6a2 transcripts, which has thus far been reported in only 26 cases of leukemias.

, a gram-negative bacillus, has varied clinical manifestations with septicemia as the most lethal. PA infection is usually regarded as opportunistic and often nosocomial. We present a case of a "healthy" pediatric patient presenting with upper respiratory symptoms who rapidly deteriorated.

Patients with A20 haploinsufficiency (HA20) presenting with central nervous system (CNS) symptoms are rare, and available reports are limited. Here, we describe a patient with HA20, previously followed up as Behçet disease, who presented with CNS symptoms in adulthood. A 38-year-old Japanese male who had been followed up for incomplete Behçet disease at another hospital since 28 years of age presented to our hospital with acute-onset diplopia and persistent hiccups that were severe enough to cause vomiting.
