Background: SHOX-D is rarely diagnosed in early infancy as cause of short stature.Objective and hypotheses: Describe clinical characteristics of two girls with an early diagnosis of Leri-Weill dyschondrosteosis, admitted to our hospital because of severe short stature.Method: Mutation screening of SHOX and its regulatory regions was performed by MLPA. Family analysis was undertaken.Results: The first 1.3 year...

Background: Cleidocranial dysplasia (CCD; MIM 119600) is a rare congenital autosomal dominant skeletal dysplasia characterized by hypoplastic or aplastic clavicles, late closure of the fontanelles, open skull sutures, dental anomalies, moderately short stature and a variety of other skeletal features. CCD is caused by mutations, deletions or duplications in the runt-related transcription factor 2 gene (RUNX2), which encodes for a protein essential for osteoblast differentiatio...

Background: VDDR-II, is an autosomal recessive disorder characterized by the early onset of rickets with hypocalcemia, secondary hyperparathyroidism and hypophosphatemia and is caused by mutations in the vitamin D receptor (VDR) gene.Objective and hypotheses: 2 years old Turkish girl first offspring of consanguineous parents admitted to the hospital for the evaluation of total alopecia and bilaterally genu varum deformity. She was born with normal pilosi...

Background: Achondroplasia and hypochondroplasia are more frequent types of skeletal dysplasia. De novo mutations in the fibroblast growth factor receptor 3 (FGFR3) gene are the principal cause. More than 95% of the cases of achondroplasia result from a mutation G1138A (Gly380Arg). In hypochondroplasia we usually (50–70%) found the change C1620A y C1620G, N540K (Asn540Lys).Objective and hypotheses: We describe an skeletal dysplasia...

Background: We already described a partial IGF1 primary deficiency due to an exon 4 homozygous missense mutation (g.65941 G>A). A few patients are now described with a heterozygous IGF1 deletion or mutation, questioning about IGF1 haplo insufficiency role in short stature.Results: We describe a boy born from consanguineous parents, with an intra uterine growth restriction (IUGR). Birth weight: 2520 g (−1 SDS) birth length: 46 ...

Introduction: Xanthogranulomatous hypophysitis (XGH) is a very rare form of pituitary hypophysitis that may present both clinically and radiologically as a neoplastic lesion or craniopharyngioma. Our case series compares the paediatric and adult presentations of XGH and the differential diagnoses considered.Case series: Patient 1: A 15-year-old female presented with refractory headache, lethargy, short stature, delayed growth (weight (−3.3...

Background: Multiple anterior pituitary hormone deficiency (MPHD) may present in the newborn period or in early infancy with hypoglycemia, prolonged cholestatic jaundice micropenis, undescended testes due to GH, ACTH, and LH deficiency. Central hypothyroidism is becoming manifest later, less severe than primary hypothyroidism, usually without intellectual impairment. A male patient was admitted to our clinic with severe short stature at the age of 2 years, born with normal len...

Background: Many children with short stature (defined as height SDS <−2S.D.) have no identified cause for their growth impairment and are classified as either small for gestational age or idiopathic short stature depending on birth size. Whole exome sequencing (WES) is a useful tool to identify new genetic diagnoses in this group. Here we describe a recurrent NDUFB3 mutation in children with intra-uterine growth retardation, short stature and ...

Background: Primordial dwarfism (PD) is a phenotype characterized by profound growth retardation and microcephaly that is prenatal in onset. Recently mutations in genes involved in ciliogenesis have been described in patients with primordial dwarfism phenotype. In 2012 mutations in rotatin (RTTN), a protein involved in cilia structure and function, have been described in in individuals with bilateral diffuse polymicrogyria, but not growth failure.Case pr...

Background: Proprotein convertase subtilisin/kexin types 1 and 2 (PCSK1 and PCSK2) are expressed in neuroendocrine tissues where they cleave a subset of inactive prohormones into biologically active hormones, including pro-opiomelanocortin (POMC), proTRH, proinsulin, proglucagon, and proGnRH. Congenital deficiency of PCSK1 is a very rare syndrome causing malabsorptive diarrhea contrasting with severe early-onset obesity and hypopituitarism. We described here a new case of cong...
