Diaphanospondylodysostosis: Full Case Report with Novel Pathogenic BMPER Mutation

Diaphanospondylodysostosis is an extremely rare, recessively inherited, perinatal lethal skeletal disorder associated with BMPER gene mutations. Clinically it is characterized by defects in costovertebral ossification, absent ribs, hypertelorism, short nose with depressed nasal bridge, low-set ears, and short neck. At the extraosseous level, the most frequent pathologic finding is nephroblastomatosis with multicystic kidneys. We present the case of a child of non-consanguineous parents who died at 2 months of age in our center. Autopsy showed a marked costovertebral ossification defect, perilobar nephrogenic rests and loss of white matter with periventricular leukomalacia. After genetic study, the diagnosis of diaphanospondylodysostosis was confirmed. A previously undescribed germinal mutation in the BMPER gene (c.576 + 2dupT) was found.

Larsen syndrome

<p>Larsen syndrome is a rare inherited disorder characterized by congenital dislocation of multiple joints along with other anomalies of heart, face, hands and bones. Larsen syndrome was first described in 1950 by Larsen, Schottstaedt and Bost. In the present report, we describe a 10 year old girl who presented with mid facial hypoplasia with depressed nasal bridge, high arched palate, bilateral talipes equinovarus and high arched feet. On examination, she had short stature (HAZ -3.5 SD) with hyperextension of knee joint, fixed flexion of elbow joint. Awareness of this condition and associated complications may help in management and follow up of these patients.</p><p> </p>

Rhizomelic Chondrodysplasia Punctata (RCDP) in a Newborn

A female newborn baby presented with the features of Rhizomelic chondrodysplasia Punctata (RCDP) characterized by rhizomalic shortening with contracture of lower extremities, ichthyosis, microcephaly, dysmorphic facial features including a depressed nasal bridge, hypoplastic midface, full cheeks & low set ear, breathing difficulties and anthropometric measures below the expected indexes for her age. The patient also presented congenital heart disease, a less common manifestation of the syndrome. Radiological features include epiphyseal stippling & Journal of Bangladesh College of Physicians and Surgeons Vol. 32, No. 3, July 2014 multiple calcification in the epiphyseal cartilage, metaphyseal flaring and clefts in vertebral bodies. It is a rare autosomal recessively inherited skeletal dysplasia. The prognosis is bad and death usually occurs within the first year of age. We report a case of neonatal RCDP which was diagnosed based on the typical clinical and radiological features.J Bangladesh Coll Phys Surg 2014; 32: 174-177

Chondrodysplasia Punctata

We report a case of two and a half months old male child affected by chondrodysplasia punctata, a rare condition characterized by depressed nasal bridge, hypoplastic distal phalanges and epiphyseal stippling of the bones.

GM1 gangliosidosis: Case report

Introduction. Gangliosidoses occur due to inhereted deficiency of human ? - galaktosidase,resulting in the accumulation of glicophyngolipides within the lisosomes. Clinical manifestations of lysosomal storage disorders are remarkably heterogeneous, they can appear at any age and each of them can vary from mild to severe conditions. Case report. We present a patient with an early, infintile type of GM1 gangliosidosis. The facial features were coarse: hypertelorismus, wide nose, depressed nasal bridge with lingual protrusion. From the very first months of life she had severe generalized hypotonic, delayed development and hapatosplenomegaly. Before she died, when she was 13 months old, she had not had any spontaneus movements, she was deaf and blind, dispnoic, with apnoiccrises, with amimic face, but without seizures and decerebrate rigidity, which often accompanies the terminal stage of this illness. Conclusion. The absence of ?-galaktosidase enzyme activaty at the skin fibroblasts confirmed the definitive diagnosis. There has been no successful treatment so far, but increasingly better results of the gene therapy for other lysosomal storage disorders can make us optimistic.

Distal Trisomy of 10q with Distal Monosomy of 15q Due to a Paternal Translocation

Distal trisomy of 10q is a rare chromosomal abnormality. Distal deletions of the terminal long arm of chromosome 15 have rarely been described. We report on a male infant with low birth weight and microcephaly, a flat face with a spacious forehead, low-set ears, blepharophimosis, microphthalmia, a small nose, and a depressed nasal bridge. Microarray comparative genomic hybridization identified that he had the karyotype 46, XY, der (15) t (10;15) (q25.2;q26.2) pat, with chromosomal breakpoints at 10q25.2 and 15q26.2. This male neonatal case had an unbalanced translocation inherited from his father who was a balanced carrier with the karyotype 46, XY, t (10;15) (q25;q26). The neonate had a partial trisomy of the long arm of chromosome 10 with a partial monosomy of distal 15q. The clinical features were in agreement with previous descriptions and allowed us to propose a growth retardation phenotype for this neonate case.

An Unusual Ocular Finding Associated With Chromosome lq Deletion Syndrome

To the Editor.— We report an unusual ocular finding associated with the chromosome lq deletion syndrome in a full-term black girl for whom there was no family history of congenital anomalies, fetal wastage, consanguinity, or drug ingestion. The infant was overtly microcephalic (third percentile) with a sloping forehead, metopic sutures open to the brow, and a large posterior fontanel. She had a low anterior hair line, depressed nasal bridge, bulbous nose, thin down-turned lips, prominent philtrum, malformed ears, and a webbed neck.
