Deletion of PREPl causes growth impairment and hypotonia in mice. [PDF]
Genetic studies of rare diseases can identify genes of unknown function that strongly impact human physiology. Prolyl endopeptidase-like (PREPL) is an uncharacterized member of the prolyl peptidase family that was discovered because of its deletion in ...

Exome and Genome Sequencing to Diagnose the Genetic Basis of Neonatal Hypotonia: An International Consortium Study. [PDF]
Background and ObjectivesHypotonia is a relatively common finding among infants in the neonatal intensive care unit (NICU). Consideration of genetic testing is recommended early in the care of infants with unexplained hypotonia.

Coincidence of Nemaline Myopathy and Agenesis of Corpus Callosum in a Newborn Infant: Case Report
The diagnosis of the hypotonia at the neonatal period is difficult. In the neonatal period, the differential must include acute illnesses and systemic diseases such as sepsis, congestive heart failure and inborn errors of metabolism. Congenital disorders

Severe neonatal hypotonia due to <i>SLC30A5</i> variant affecting function of ZnT5 zinc transporter. [PDF]
The tightly‐regulated spatial and temporal distribution of zinc ion concentrations within cellular compartments is controlled by two groups of Zn2+ transporters: the 14‐member ZIP/SLC39 family, facilitating Zn2+ influx into the cytoplasm from the ...
