Background: FLNB encodes filamin B (FLNB), a protein expressed in human growth plate chondrocytes, building the cytoskeleton that gives structure to cells and allows them to change shape and move. Biallelic loss-of-function mutations in FLNB result in spondylocarpotarsal synostosis (SCT; OMIM: 272460), while heterozygous null mutations related isolated short stature (ISS) have not been well described previously.Objective:</strong...

Objective: To explore the clinical manifestations and genetic characteristics of 10 patients with ACAN variants presented as short stature, and analyze the efficacy of recombinant human growth hormone (rhGH) and/or combined with gonadotropin-releasing hormone agonist (GnRHa) in some patients with premature thelarche.Methods: We reviewed clinical data of 10 patients with ACAN variants. Genetic testing was performed on pro...

Objective: To investigate the clinical efficacy of GnRHa in the treatment of girls with post-menarche in ICPP or rapidly progressive puberty（RPP）. To analyze the effect of GnRHa combined with rhGH on growth velocity (GV) and predicted adult height (PAH) in the process of GnRHa treatment with too low growth velocity.Methods: Retrospective analysis of the clinical data of 55 post-menarche ICPP/RPP girls withi...

Objective: To highlight the clinical characteristics and early genetic diagnosis of Schaaf-Yang syndrome (SYS).Methods: Three cases were reported and related literature were reviewed.Results: All the three patients were diagnosed with Schaaf-Yang syndrome attributing to the variation of MAGEL2 gene. Two of the patients predominantly presented as "language dysplasia&#34...

Objective: To report a case girl with 45X/47XXX mosaic Turner syndrome exhibiting a progressive puberty.Design: Case reportResult: A 9 years 4 months old girl was presented with growth retardation. Chromosome analysis revealed a mosaic karyotype 45X/47XXX. She presented with normal height but much lower than the mid-parental height. During annual check-ups, her growth rate was acce...

Background: Laron syndrome (LS), (OMIM#262500) is a rare recessively inherited disease caused by deletions or mutations of the GH receptor, and is characterized by low or undetectable serum IGF-I. This deficiency leads to a series of metabolic abnormalities including of the proteins.Subjects & Method: This study presents for the first time the amino-acid analysis of two untreated and one IGF-I treated LS patients using the LC-MS/MS method (Waters TQS...

Background: Congenital hypothyroidism (CH) is a common endocrine disorder with a prevalence ranging from 1:2000 to 1:4000 newborns. The majority of CH cases were reported to be associated with mutations in several genes, which including the TSH receptor gene (TSHR).Objective and hypotheses: The aim of this study is to examine the frequency of TSHR gene mutations among CH patients in the Guangxi Zhuang Autonomous Region of China and to discover correlatio...

Objective: In boys during puberty who were undergoing recombinant human growth hormone (rhGH) treatment, we compared the therapeutic efficacy and any adverse reactions, of co-therapy with letrozole/gonadotropin releasing hormone analog (GnRHa).Methods: Fifty-six pubertal growth hormone deficiency (GHD) boys were studied, they were treated with the combination of letrozole and rhGH (letrozole group) or GnRHa and rhGH (GnR...

Context: Kenny–Caffey syndrome (KCS) is a rare condition characterized by proportionate short stature, cortical thickening and medullary stenosis of tubular bones, delayed closure of the anterior fontanelle, ocular and dental anomalies, and variable hypocalcemia due to hypoparathyroidism. KCS is classified into two types according to its clinical features and inheritance pattern. KCS Type 2 (KCS2) is caused by mutations in FAM111A and is distinguished fr...

Objectives: To compare the levels of E2 in girls measured by LC-MS/MS and CLIA, and to evaluate the correlations between E2 levels and bone age, uterine length, and uterine volume.Methods: 133 newly diagnosed girls were selected. There were 80 girls in the ICPP group (44 in the Tanner II stage in the ICPP group, 36 in the Tanner III in the ICPP group), and 53 in the PT group， 40 healthy girls in the Tanner III gro...
