Hundreds of genes reside in structurally complex, poorly understood regions of the human genome. One such region contains the three amylase genes (AMY2B, AMY2A and AMY1) responsible for digesting starch into sugar. Copy number of AMY1 is reported to be the largest genomic influence on obesity, although genome-wide association studies for obesity have found(More)
CONTEXT Microcephalic primordial dwarfism (MPD) is a rare, severe form of human growth failure in which growth restriction is evident in utero and continues into postnatal life. Single causative gene defects have been identified in a number of patients with MPD, and all involve genes fundamental to cellular processes including centrosome functions. (More)
CONTEXT The majority of patients presenting with short stature do not receive a definitive diagnosis. Advances in genetic sequencing allow for large-scale screening of candidate genes, potentially leading to genetic diagnoses. OBJECTIVES The purpose of this study was to discover genetic variants that contribute to short stature in a cohort of children(More)
OBJECTIVES Recent data from mainly homogeneous European and African populations implicate a 140-bp region 5' to the transcriptional start site of LCT (the lactase gene) as a regulatory site for lactase persistence and nonpersistence. Because there are no studies of US nonhomogeneous populations, we performed genotype/phenotype analysis of the -13910 and(More)
Langer-Giedion syndrome (LGS; MIM 150230), also called trichorhinophalangeal syndrome type II (TRPS2), is a contiguous gene syndrome caused by a one-copy deletion in the chromosome 8q23-q24 region, spanning the genes TRPS1 and EXT1. We identified an LGS family with two affected and two unaffected siblings from unaffected parents. To investigate the etiology(More)
BACKGROUND Primary nonautoimmune hyperthyroidism is a rare cause of neonatal hyperthyroidism. This results from an activating mutation in the thyrotropin-receptor (TSHR). It can be inherited in an autosomal dominant manner or occur sporadically as a de novo mutation. Affected individuals display a wide phenotype from severe neonatal to mild subclinical(More)
BACKGROUND/AIMS Short stature is a common reason for presentation to pediatric endocrinology clinics. However, for most patients, no cause for the short stature can be identified. As genetics plays a strong role in height, we sought to identify known and novel genetic causes of short stature. METHODS We recruited 14 children with severe short stature of(More)
Based on the observation of reduced stature in relatives of patients with acromesomelic dysplasia, Maroteaux type (AMDM), caused by homozygous or compound heterozygous mutations in natriuretic peptide receptor-B gene (NPR2), it has been suggested that heterozygous mutations in this gene could be responsible for the growth impairment observed in some cases(More)
CONTEXT Short stature is a common reason for referral to pediatric endocrinology centers. Frequently, the underlying etiology of short stature is unknown, resulting in a diagnosis of idiopathic short stature. Rare genetic defects in the GH/IGF-1 axis have been found to cause short stature. OBJECTIVE The objective of this study was to identify the genetic(More)
