Longitudinal study of growth 1995-2017. Longitudinal studies of growth require a very long follow-up period, about 20 years, but they allow to correctly evaluate pubertal growth by providing differentiated data for children who initiate pubertal maturation at an early, intermediate or late time. In this study, 1,453 healthy non-obese subjects (743 women, 710 males) who reached adult height between January 2012 and January 2017 were included, which allowed the development of height, weight and body mass index charts, with the particularity of including separated charts for the different phenotypes of pubertal maturation (very early, early, intermediate, late and very late). This allows a much more accurate assessment of pubertal growth.

In addition to the publication of the results, a website "Millennials Growth. Longitudinal growth study 1995-2017", which includes the growth charts performed with the LMS method, an auxologic calculation program for health professionals, and two Apps (Android and iOS) has been developed. This will allow their use by all health professionals and we believe it will be a very valuable tool for the assessment and monitoring of normal and pathological growth in children.

4.1 Disorders of sex development (DSD): clinical and molecular diagnosis. We analyse known genes involved in human sexual differentiation and search for new genes.

4.2 Program of molecular diagnosis of thyroid dyshormonogenesis in patients with hypothyroidism which have been diagnosed at the newborn screening program. The objective of this project is to advance in the identification and characterization of the molecular basis of the patients with thyroid dyshormonogenesis through the implementation of next generation sequencing techniques (NGS) to later translate these results to the routine diagnosis of the detected patients in the program of Neonatal Screening of Congenital Hypothyroidism. Our group is reference centre for Catalonia. 4.3 Familial isolated glucocorticoid deficiency: clinical and molecular diagnosis. We analyse known genes involved in familial isolated glucocorticoid deficiency and search for new genes.

4.4 Congenital hyperinsulinism: clinical and molecular diagnosis. We analyse known genes involved in congenital hyperinsulinism and search for new genes.
