Significance of GNAS mutations for morbid obesity in children.

ABSTRACT:

Background

Hereditary forms of obesity are characterized by early severe heterogeneous manifestations of the phenotype along with a rapid progression to morbid obesity, primary due to pathogenic variants of certain genes. Most forms are characterized by moderate to severe neuropsychic developmental delays, dysmorphic features and organ-specific developmental anomalies.

Result

We searched for hereditary causes of morbid obesity in children by exome sequencing. As a result, we have identified 5 variants in the GNAS locus, two of which were identified for the first time: NM_000516.7(GNAS):c.201del, (p.Phe68Leufs*32) and NM_000516.7(GNAS):c.586 - 18_591del. Children showed tolerance to parathyroid hormone and thyroid-stimulating hormone. It has been observed that almost all the
