Central precocious puberty due to hypothalamic hamartomas correlates with anatomic features but not with expression of GnRH, TGFalpha, or KISS1.
BACKGROUND/AIMS Hypothalamic hamartomas are the most common identifiable cause of central precocious puberty (CPP). Hamartoma characteristics proposed to be associated with CPP include specific anatomic features and expression of molecules such as gonadotropin-releasing hormone (GnRH), transforming growth factor alpha (TGFalpha), and GRM1A, which encodes the type 1 metabotropic glutamate recept...

Background/Aims: Hypothalamic hamartomas are the most common identifiable cause of central precocious puberty (CPP).

متن کاملGene expression profiling of hypothalamic hamartomas: a search for genes associated with central precocious puberty.
BACKGROUND Hypothalamic hamartomas (HHs) are congenital lesions composed of neurons and astroglia. Frequently, HHs cause central precocious puberty (CPP) and/or gelastic seizures. Because HHs might express genes similar to those required for the initiation of normal puberty, we used cDNA arrays to compare the gene expression profile of an HH associated with CPP with three HHs not accompanied by...
متن کاملCentral precocious puberty secondary to hypothalamic hamartoma
Introduction Central precocious puberty (CPP) presenting at a very young age is likely to have an underlying pathology. One of the pathologies is hypothalamic hamartoma (HH), a non-neoplastic tumour-like lesion located at the floor of the third ventricle, near the tuber cinereum. Two young children with CPP due to HH without gelastic seizures or mental retardation were successfully managed and ...
متن کاملIs precocious puberty linked to hypothalamic expression of arginine-phenylalanine-amide-related peptide?
The up-regulator regulation and down-regulator regulation of gonadotropin-releasing hormone (GnRH) in central precocious puberty is not yet known. However, recent advances in neuroendocrinology have shown the controlling role of arginine-phenylalanine (RF)-amide-related peptides (RFRPs) on GnRH secretion in different phenomenon of reproduction such as estrus cycle and pregnancy, but the exact r...
