NGS +

[Sanger]

Groupe of diseases: Hypoglycaemia + familial hyperinsulinism range from severe neonatal onset to childhood onset with mild symptoms. Neonatal-onset disease manifests within hours to days after birth. In the newborn period, presenting symptoms may be nonspecific, including seizures, hypotonia, poor feeding, apnea. Childhood-onset disease manifests during the first months/years of life, can present with an unprovoked seizures or be asymptomatic. Within the same family, symptom manifestations can range from mild to severe.
