Incidence of 4 Lysosomal Storage Disorders from 4 Years of Newborn Screening

The Missouri State Public Health Laboratory (MSPHL) recently published findings on incidence rates from 4 years of full population newborn screening for Pompe, MPS I, Gaucher and Fabry lysosomal storage disorders (LSDs) using the digital microfluidic platform SEEKER. The Missouri program is the longest-running prospective and un-blinded newborn screening and follow-up study of LSDs in the United States. In the first 4 years of LSD screening, the MSPHL identified 133 newborns who were confirmed through diagnostic testing to have one of the four LSDs. The incidence rates for Pompe and Fabry found in Missouri correlate well with results from Taiwan but are higher than recently reported incidence rates in Illinois. Incidence rates for Gaucher and MPS I correlate well to other pilot studies. The MSPHL has not identified any missed LSD cases to date.

Electrowetting Droplet Operations on a Digital Microfluidic Cartridge

Simple droplet operations of dispensing from a reagent reservoir, droplet transport across electrodes, merging two droplets into a larger combined droplet, mixing the combined droplet, and splitting the droplet are accomplished by strategically applying voltages to electrodes on the cartridge printed circuit board.

Baebies Supports Recommendation for Expanded Newborn Screening in NC

At Baebies, our mission drives us to support the acceleration of expanding newborn screening wherever and whenever possible. Baebies was mentioned in a recent report generated by the North Carolina Advisory Council on Rare Diseases called, “Newborn Screening and Early Intervention for the Treatment of Rare Diseases: A Win-Win for Children with Rare Diseases and North Carolina.” North Carolina pioneered universal screening of newborns using tandem mass spectrometry for metabolic disorders, developed at Duke University by Prof. David Millington (Baebies Advisor). The report, published earlier this year, highlights the ecosystem in NC comprising academia (Duke and UNC), non-profit (Research Triangle Institute), and industry (Baebies) that can drive innovations in newborn screening with significant impact for babies around the world.

Understanding Enzyme Assays for Lysosomal Storage Disorders – The Influence of Substrate Concentration and Incubation Time (Part IV)

The fourth and final white paper in our series reviews several concepts of enzyme assays for lysosomal storage disorders (LSDs). To wrap up the series, Baebies examines all the factors that determine enzyme activity and highlights how enzyme assays can be performed with shorter incubation times without incurring additional cost or compromising assay performance. This is especially significant in the case of newborn screening of Pompe disease, where timely intervention results in better outcomes for the patients.

Understanding Enzyme Assays for Lysosomal Storage Disorders – Integration of X-linked Adrenoleukodystrophy and SEEKER Workflows for Same-Day Referrals (Part III)

The recent additions of two lysosomal storage disorders (Pompe and MPS I) and a peroxisomal metabolic disorder (X-ALD) to the RUSP have led several labs to discuss adding these disorders to their screening panels. Our “Understanding Enzyme Assays for Lysosomal Storage Disorders” white paper series has examined key differences between enzymatic versus metabolic assays on digital microfluidics (FDA authorized) or tandem mass spectrometry (MS/MS) platforms. The series continues with a focus on the different screening methods for LSDs and X-ALD and how to optimize laboratory workflows when adding X-ALD.

Understanding Enzyme Assays for Lysosomal Storage Disorders – How to Measure Product Formation (Part II)

Enzyme assays for lysosomal storage disorders (LSDs) are performed by using either digital microfluidics (FDA authorized) or tandem mass spectrometry (MS/MS) platforms. Part 1 of the “Understanding Enzyme Assays for Lysosomal Storage Disorders” series outlines the difference between natural and artificial substrates and how they are deployed on each platform. Although MS/MS platforms are often already installed in most labs for metabolic assays, key differences in assay protocols and workflows need to be evaluated to examine if it would be feasible to share the equipment. Part 2 of this series explains this further and examines the time it takes for each method workflow, including the steps and equipment necessary.

Baebies Announces Completion of $10 Million Series B Financing

Baebies, a growth-stage company that delivers innovative products and services for newborn screening and pediatric testing, today announced that it has secured $10 million in Series B financing in an oversubscribed round anchored by BOE Technology Group Co., Ltd. BOE is a global leader in semiconductor display industry as well as an IoT company providing intelligent interface products and services for information interaction and human health. Baebies also received funding from family offices, with continued support from current investors and the North Carolina Biotechnology Center.

Understanding Enzyme Assays for Lysosomal Storage Disorders – Synthetic Substrates (Part I)

High throughput testing of multiple lysosomal storage disorders (LSDs) from dried blood spots can be performed using digital microfluidics (FDA authorized) or tandem mass spectrometry. Although both methods use “artificial” substrates to perform enzymatic reactions, digital microfluidics runs each reaction at its optimal pH.
