X-linked dominant hypophosphatemic rickets (XLH) are the most common form of familial hypophosphatemic rickets resulting from hypophosphatemia caused by renal phosphate wasting, which in turn is a result of loss-of-function mutations in PHEX. Herein, we report a 39-year-old female with short stature and skeletal deformities and 12-month-old asymptomatic daughter. The woman has a history of multiple surgical treatments because of lower limb deformities. Through additional quest...

1q21.1 recurrent microdeletion syndrome is a rare chromosomal disorder caused by a genetic abnormality of non-allelic homologous recombination in the sequence of flanking a copy number variation event during meiosis. The characteristic features of 1q21 microdeletion syndrome are dysmorphic facial appearances with microcephaly, and mild to moderate developmental delay of speech and motor, eye abnormality, short stature, skeletal malformation, and psychiatric and behavioral diso...

20 months old girl has frequent hypoglycemias, protruding forehead(frontal bossing), sunken bridge of the nose (saddle nose), and a blue tint to the whites of the eyes (blue sclerae). short limbs compared to the size of her torso, as well as small hands and feet, fragile thin hair,short limbs, Genu varum, Brachydactyly,malar falttening, motor delay, delayed teeth eruption, when plotted to growth chart height found far below the third centile for age,sex,population, Hre laborat...

Introduction: Acromesomelic Dysplasia of Maroteaux (AMDM) is a cause of severe short stature (final height below120cm) with shortening of the middle and distal segments of the limbs, caused by homozygous or heterozygous mutations in the NPR2 gene which encodes natriuretic peptide receptor B on chromosome 9p13Case report: The proband was 4y6mo old, second born to 3rd degree consanguineous parents and presented ...

2 siblings were referred for evaluation fo short stature and failure to thrive. Both were born of 3rd degree consanguinity, first and second in birth order. the first sibling was 2 1/2 year old at time of referral and had birthweight of 3.1 kg and had gross motor delay. Present height was 65 cm (SDS −6.2 S.D.)and weight was 6 kg (<3rd centile) Second sibling was 1.5 years old, with gross motor delay with height of 57 cm (SDS −6.5 S.D.</sma...

We present the case of a 7-year-old female affected by permanent congenital hypothyroidism and Bannayan-Riley-Ruvalcaba syndrome. The patient was born at 31+4 gestational weeks because of premature rupture of membranes. At birth her auxological parameters were adequate for gestational age with a 75th percentile head circumference. She was diagnosed with congenital hypothyroidsm (TSH 1016 mcu/ml, FT4 <0.4 ng/dl) with an in situ gland caused by a homozygous mutation...

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: Interstitial deletions of the short arm of chromosome 11 are rare chromosomal anomalies, and are considered to be associated with several clinical conditions including WAGR syndrome.Objective: To report the clinical and molecular findings in the first case of a heterozygous 11p14.1-p15.3 deletion.Patient: A Japanese female patient was born at 39 weeks of gestation after an uncomplicated pregnancy and delivery. At birth,...

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...
