Bi-allelic variants in HMGCR cause an autosomal-recessive progressive limb-girdle muscular dystrophy.

Statins are a mainstay intervention for cardiovascular disease prevention, yet their use can cause rare severe myopathy. HMG-CoA reductase, an essential enzyme in the mevalonate pathway, is the target of statins. We identified nine individuals from five unrelated families with unexplained limb-girdle like muscular dystrophy and bi-allelic variants in HMGCR via clinical and research exome sequencing.

Patient uptake of updated genetic testing following uninformative BRCA1 and BRCA2 results.

Advances have dated the genetic testing initially offered to evaluate for hereditary breast and ovarian cancer risks. Previous research has demonstrated that many patients have not updated testing. This study reviewed the incidence of additional analysis after an uninformative BRCA1/2 result and offered updated testing with limited barriers to those who had not completed.

Functional validation of a novel AAAS variant in an atypical presentation of Allgrove syndrome.

Background: Achalasia-addisonianism-alacrima syndrome, frequently referred to as Allgrove syndrome or Triple A syndrome, is a multisystem disorder resulting from homozygous or compound heterozygous pathogenic variants in the gene encoding aladin (AAAS). Aladin is a member of the WD-repeat family of proteins and is a component of the nuclear pore complex. It is thought to be involved in nuclear import and export of molecules.

Impact of integrated translational research on clinical exome sequencing.

Purpose: Exome sequencing often identifies pathogenic genetic variants in patients with undiagnosed diseases. Nevertheless, frequent findings of variants of uncertain significance necessitate additional efforts to establish causality before reaching a conclusive diagnosis. To provide comprehensive genomic testing to patients with undiagnosed disease, we established an Individualized Medicine Clinic, which offered clinical exome testing and included a Translational Omics Program (TOP) that provided variant curation, research activities, or research exome sequencing.

Case report expanding the germline AXIN2- related phenotype to include olfactory neuroblastoma and gastric adenoma.

Background: Pathogenic AXIN2 variants cause absence of permanent teeth (hypodontia), sparse hair and eye brows (ectodermal dysplasia), and gastrointestinal polyps and cancer. Inheritance is autosomal dominant with variable penetrance. Only twenty- five patients have been reported from five families.

Retrospective review of outcomes in patients with DNA-damage repair related pancreatic cancer.

Background: Patients with DNA-damage response genes (DDR)-related pancreas cancer ( or other DNA-damage related genes) may have improved outcomes secondary to increased sensitivity to DNA-damaging drugs (platinum chemotherapy/ poly ADP ribose polymerase (PARP)-inhibitors). However, data is scarce pertaining to outcomes in this subset of patients. Our objective was to retrospectively identify DDR-related pancreas cancer patients and report on clinical outcomes.
