Ectodermal dysplasia syndactyly syndrome 1 (EDSS1) is a rare form of ectodermal dysplasia including anomalies of hair, nails, and teeth along with bilateral cutaneous syndactyly of hands and feet. In the present report, we performed a clinical and genetic characterization of a consanguineous Pakistani family with four individuals affected by EDSS1. We performed exome sequencing using DNA of one affected individual. Exome data analysis identified a novel homozygous missense variant (c.242T>C; p.(Leu81Pro)) in NECTIN4 (PVRL4)...

Congenital anomalies of the upper limbs are rare and etiologically heterogeneous. Herein, we report a male infant with non-syndromic bilateral Type Vb ulnar longitudinal dysplasia with radiohumeral synostosis (apparent humeral bifurcation), and bilateral oligo-ectro-syndactyly who was born following an uncomplicated pregnancy, with no maternal use of prescription or illicit medication. Array CGH (60,000 probes) and chromosomal breakage analysis (DEB) were normal. Similar appearances have been reported in children exposed to thalidomide or cocaine, but sporadic patients have also been reported without a prior history of exposure to known teratogens...

Bardet-Biedl Syndrome (BBS) is a rare multi-systemic disease with autosomal recessive transmission. BBS was at first considered to be homogeneous as for its genetics, but subsequent studies have shown an extensive gene variability. Currently, 21 genes (BBS1-21) present on different chromosomes have been mapped: these genes are responsible for BBS phenotypes and they show a great heterogeneity of mutations.The most common genes are BBS1 (locus 11q13) and BBS10.We show here the case of a 50 year old patient with BBS...

Lewis B Holmes, Marie-Noel Westgate, Hanah Nasri, M Hassan Toufaily
BACKGROUND: Several malformations have been attributed to the process of vascular disruption. The central hypothesis for this etiology is that blood flow to a structure has been altered after that structure had formed normally. The decreased blood flow leads to hypoxia, endothelial cell damage, hemorrhage, tissue loss, and repair. After recovery, some structures are normal and others show either tissue loss or structural abnormalities, such as syndactyly and constriction rings. METHODS: The phenotypic features of the 7,020 infants with one or more malformations, who were born to women who had always planned to deliver at Brigham and Women's Hospital (BWH) between, 1972 and 2012, that is, maternal nontransfers, were reviewed...

Whole-exome and targeted sequencing of 13 individuals from 10 unrelated families with overlapping clinical manifestations identified loss-of-function and missense variants in KIAA1109 allowing delineation of an autosomal-recessive multi-system syndrome, which we suggest to name Alkuraya-Kučinskas syndrome (MIM 617822). Shared phenotypic features representing the cardinal characteristics of this syndrome combine brain atrophy with clubfoot and arthrogryposis. Affected individuals present with cerebral parenchymal underdevelopment, ranging from major cerebral parenchymal thinning with lissencephalic aspect to moderate parenchymal rarefaction, severe to mild ventriculomegaly, cerebellar hypoplasia with brainstem dysgenesis, and cardiac and ophthalmologic anomalies, such as microphthalmia and cataract...

Polydactyly is a relatively common abnormality in infants. However, it can be a marker of a wide variety of neurological and systemic abnormality. Hence, it is important for pediatrician and physician to have insight into the various association of this apparently innocuous anomaly. In this write-up, we report an extremely rare syndrome associated with polydactyly that is Pallister-Hall syndrome. A 10-month-old male child born by lower segment cesarean section presented with global delay associated with microcephaly, frontal bossing, hypertelorism, flat nose, short philtrum, incomplete cleft in the upper lip and hard palate, polydactyly, and syndactyly...

Fraser syndrome is a rare autosomal recessive disorder characterized by renal agenesis, cryptophthalmos, syndactyly, and laryngeal stenosis. Oral manifestations are sparsely described in the literature, and patients with this syndrome might require special dental management considerations because of the associated cardiac, renal, and cognitive defects. In this report, we describe the oral/dental findings in a 22-year-old girl with Fraser syndrome, and discuss the dental management.

Pfeiffer syndrome is a rare hereditary condition with an autosomal dominant transmission caused by a mutation that affects fibroblast growth factor receptors. It is one of the acrocephalosyndactyly diseases causing cranial malformations owing to early suture fusion. In the foot, it is typically associated with hallux varus, first ray hyperplasia, and partial lesser digit syndactyly. We report a clinical case of a 10-year-old patient with Pfeiffer type I syndrome with bilateral severe hallux varus due to a hypoplastic trapezoidal shaped proximal phalanx, a distal, medial-facing articular surface, and interphalangeal instability...

BACKGROUND: Apert Syndrome (AS), or type I acrocephalosyndactyly, is a rare, congenital craniosynostosis condition resulting from missense mutations in the gene encoding fibroblast growth factor receptor 2. It is characterized by three specific clinical features: brachycephalic skull; midface hypoplasia, and limb abnormalities (syndactyly of hands and feet). The disorder exhibits variable presentations in bones, brain, skin, internal organs, and in the oral/maxillofacial region. The aim of the present paper was to show the main results from a systematic review of AS...

Baraitser-Winter syndrome was first described as a syndrome of iris coloboma, ptosis, hypertelorism, and mental retardation (Baraitser and Winter 1988; Baraitser, 2016). The phenotypic spectrum has since broadened to include other facial dysmorphic features, deafness, microcephaly, lissencephaly, and CNS findings (Baraitser and Winter 1988; Ganesh et al., 2005; Henedy et al., 2010; Verloes et al., 2015). The syndrome is due to pathogenic variants on either ACTB or ACTG1 genes (Di Donato et al., 2014; Rivière et al...

Fibroblast growth factors and fibroblast growth factor receptors (FGFRs) play important roles in human axial and craniofacial skeletal development. FGFR1, FGFR2, and FGFR3 are crucial for both chondrogenesis and osteogenesis. Mutations in the genes encoding FGFRs, types 1-3, are responsible for various skeletal dysplasias and craniosynostosis syndromes. Many of these disorders are relatively common in the pediatric population, and diagnosis is often challenging. These skeletal disorders can be classified based on which FGFR is affected...

Mutations in GLI3, which encodes a transcription factor of the Hedgehog signaling pathway, cause several developmental anomalies linked to inappropriate tissue patterning. Here, we report a novel missense variant in the fifth zinc finger domain of GLI3 (c.1826G>A; p.(Cys609Tyr)) initially identified in a proband with preaxial polydactyly type IV, developmental delay, sensorineural hearing loss, skeletal, and genitourinary anomalies. Additional family members exhibited various digital anomalies such as preaxial polydactyly, syndactyly, and postaxial polydactyly either in isolation or combined...
