Pompe disease (OMIM no 232300) is an autosomal recessive inherited metabolic disorder, caused by glycogen accumulation in the lysosome due to deficiency of the lysosomal acid 03B1-glucosidase enzyme. Here we report the case of an 8-month-old girl of consanguineous Turkish parents, who was diagnosed with the infantile form of Pompe disease. Two different uncommon homozygote mutations (c.32-13 T > G homozygote and c.1856G > A homozygote) were detected. The patient had a more progressive clinical course than expected. We emphasize the rare combination of genetic mutations in this Turkish family with Pompe disease.

Background: The current standard of care for infantile-onset Pompe disease (IOPD), a severe form of acid α-glucosidase enzyme activity deficiency is: (1) detection by newborn screening, (2) early initiation of intravenous enzyme replacement therapy (ERT) using recombinant human acid alpha-glucosidase (rhGAA), with higher doses of rhGAA increasingly used to improve clinical outcomes, and (3) immune tolerization induction (ITI) using to prevent anti-rhGAA antibody formation, with methotrexate (MTX), rituximab, and IVIG used for patients who are cross-reactive immunologic material negative (CRIM-) and monotherapy with MTX used in patients who are cross-reactive immunologic material positive (CRIM+).
Objectives/methods: A pilot study evaluates a dose-intensive therapy (DIT) using high-dose ERT (40 mg/kg/week) and more frequent exposure to ERT (i.e.

Background: Newborn screening (NBS) is a simple, non-invasive test that allows for the early identification of genetic diseases within the first days of a newborn's life. The aim of NBS is to detect potentially fatal or disabling conditions in newborns as early as possible, before the onset of disease symptoms. Early diagnosis enables timely treatments and improves the quality of life for affected patients.

Congenital neutropenia (CoN) is a heterogeneous group of inborn errors of immunity (IEI) characterized by recurrent infections and early onset of neutropenia (NP). This study aimed to investigate the demographic and clinical data of children with CoN and idiopathic neutropenia (IN) in Morocco. We performed a retrospective study of patients with CoN and analyzed the clinical and laboratory findings of patients with CoN and IN diagnosed between 1999 and 2018 in a clinical immunology unit of a large pediatric hospital.
