Whole exome sequencing reveals a dual diagnosis of BCAP31-related syndrome and glutaric aciduria III.

Journal article Mol Genet Metab Rep · September 2024 BACKGROUND: Biochemical testing is a common first-tier approach in the setting of genetic evaluation of patients with unexplained developmental delay. However, results can be unclear, and a plan for second-tier analysis must be determined based on the pati ... Full text Link to item Cite

Gaucher disease type 3c: Expanding the clinical spectrum of an ultra-rare disease.

Journal article JIMD Rep · September 2024 Gaucher disease (GD) type 3 is an autosomal recessive lysosomal disease caused by deficiency of β-glucocerebrosidase (GCase) and encompasses a spectrum of cardiac, neurological, and ophthalmological abnormalities.

Recommendations to improve the patient experience and avoid bias when prenatal screening/testing.

Journal article Disability and health journal · April 2023 While prenatal screening and testing have expanded substantially over the past decade and provide access to more genetic information, expectant parents are more likely to describe the diagnosis experience as negative than positive. In addition, the convers ... Full text Cite

Glucosylsphingosine (Lyso-Gb1): An Informative Biomarker in the Clinical Monitoring of Patients with Gaucher Disease.

Journal article Int J Mol Sci · November 29, 2022 Historically, disease burden and treatment responses in patients with Gaucher disease (GD) was assessed by monitoring clinical data, laboratory, imaging, chitotriosidase (CHITO), and other biomarkers; however, these biomarkers lack specificity and CHITO is ...
