Background: Among the currently known variants of maturity-onset diabetes of the young (MODY) subtypes 1–3 are the most prevalent, while their relative frequencies vary in different populations. Other types of MODY are more rare, although the studies addressing their prevalences are limited. Recent implementation of next-generation sequencing (NGS) enables simultaneos analysis of multiple candidate genes making it an attracive approach in various monogenic disorders, incl...

Background: 80–85% of cases of congenital hypothyroidism (CH) are shown to be due to thyroid dysgenesis, while 15–20% are due to dyshormonogenesis. At least 12 candidate genes are associated with congenital hypothyroidism (CH), however its molecular basis is defined in fewer than 10% of the patients (ESPE consensus, 2014). Recent studies suggest that using a next generation sequencing (NGS) approach may increase the mutation yield in CH.Objecti...
