Kenny-Caffey syndrome: an Arab variant?

We describe 2 unrelated Bedouin girls who met the criteria for the diagnosis of Kenny-Caffey syndrome. The girls had some unusual features--microcephaly and psychomotor retardation--that distinguish the Kenny-Caffey syndrome profile in Arab children from the classical Kenny-Caffey syndrome phenotype characterized by macrocephaly and normal intelligence. The 2 girls did not harbor the 22q11 microdeletion (the hallmark of the DiGeorge cluster of diseases) that we previously reported in another Bedouin family with the Kenny-Caffey syndrome (Sabry et al. J Med Genet 1998: 35(1): 31-36). This indicates considerable genetic heterogeneity for this syndrome. We also review previously reported 44 Arab/Bedouin patients with the same profile of hypoparathyroidism, short stature, seizures, mental retardation and microcephaly. Our results suggest that these patients represent an Arab variant of Kenny-Caffey syndrome with characteristic microcephaly and psychomotor retardation. We suggest that all patients with Kenny-Caffey syndrome should be investigated for the 22q11 microdeletion. Other possible genetic causes for the Kenny-Caffey syndrome or its Arab variant include chromosome 10p abnormalities.

New syndromic entity of situs inversus totalis.

A 22-year-old Bedouin female with MCA/MR has been recently ascertained. She showed profound mental retardation, proportionate short stature, facial dysmorphism, spastic quadreparesis, bilateral taliper equinovarus, brachydactyly, situs inversus totalis, and MRI findings of cerebellar/midbrain migration defects. The described phenotype represents a new syndromic situs inversus with a characteristic Facio-Cerebro-Skeleto-Cardiac phenotype.

The autosomal recessive congenital intrauterine infection-like syndrome of microcephaly, intracranial calcification, and CNS disease: report of another Bedouin family.

We describe a Bedouin family with the rare autosomal recessive infection-like syndrome of microcephaly, intracranial calcification and CNS disease that has so far been documented in only eight families including one from Kuwait. In the present family, the female proband had congenital microbrachycephaly, hypertonia, early-onset tonic-clonic seizures, a palpable liver and mild pulmonary stenosis. Follow-up examination of the girl identified delayed developmental milestones while head CT scan revealed partial agenesis of the corpus callosum, brain atrophy, dilated ventricles and scattered calcific foci in the caudate nuclei, the thalami, and the periventricular white matter. The possibility of intrauterine TORCH infection was excluded by the negative results of repeated immunovirology study and by the failure to recover viral inclusions in urine cultures. The proband had three apparently affected cousins with spasticity and CT findings of microcephaly and intracranial calcification. Other previously documented cases with the congenital intrauterine infection-like syndrome are reviewed.

Triophthalmia and facial clefting: a case report.

We describe a Libyan boy with an unusual phenotype of multiple congenital anomalies, including triophthalmia, dolichocephaly, porencephaly, cleft lip/palate, facial asymmetry, micrognathia, and VSD. The reported phenotype is likely to represent a new entity of non-chromosomal syndromic triophthalmia. Other possibilities are discussed.

Kenny-Caffey syndrome in six Bedouin sibships: autosomal recessive inheritance is confirmed.

We are reporting on 16 children, in 6 unrelated sibships, born to healthy, consanguineous parents of Bedouin ancestry. Eleven of them were assessed clinically. All presented with marked growth retardation, craniofacial anomalies, small hands and feet, hypocalcemia, hypoparathyroidism, radiological evidence of cortical thickening of long bones with medullary stenosis, and absent diploic space in the skull. There was a history of 6 affected sibs dying in infancy with hypocalcemic convulsions. All cases show absence of macrocephaly and early psychomotor retardation. The present cases confirm the presence of clinical variability and co firm autosomal recessive inheritance of Kenny-Caffey syndrome.

Another Arab patient with overlap of Váradi-Papp/Opitz trigonocephaly syndromes?

We describe a Bedouin boy with multiple congenital anomalies/mental retardation (MCA/MR). He has frontal bossing, ridged metopic suture, bilateral ptosis, right squint, depressed nasal bridge, small nose, anteverted nostrils, lobulated tongue, polydactyly of both hands, microphallus, hypoplastic scrotum, microtestes, dysgenesis of corpus callosum, and a Dandy-Walker variant. This phenotype overlaps both the Varadi-Papp syndrome (OFD VI) and Opitz trigonocephaly (C syndrome). This phenotypic overlap is discussed in light of the concept of splitting and lumping in genetic diseases.

Greig cephalopolysyndactyly syndrome with dysgenesis of the corpus callosum in a Bedouin family.

We report on the first known Bedouin family with Greig cephalopolysyndactyly syndrome (MIM 175700). The index patient and his father shared pre- and postaxial polysyndactyly, mild mental retardation, and corpus callosum dysgenesis. Their phenotypic findings were compared with reported cases of both Greig cephalopolysyndactyly (GCPS) and acrocallosal syndromes. This family represents the second report of the rare occurrence of dysgenesis of the corpus callosum in GCPS.

Femoral hypoplasia-unusual facies syndrome with bifid hallux, absent tibia, and macrophallus: a report of a Bedouin baby.

A male Bedouin baby with the clinical profile of femoral hypoplasia-unusual facies syndrome is described. The phenotype includes bilateral asymmetrical lower limb hypoplasia/aplasia with short remnants of both femora, absent right tibia, bifid right big toe, dysmorphic facies, thoracic/pelvic abnormalities, macrophallus, and bilateral cryptorchidism. This report re-emphasises the previously described rare association of femoral hypoplasia-unusual facies syndrome with preaxial polydactyly and suggests that the clinical spectrum of the syndrome could be stretched further to accommodate other unusual traits, for example, macrophallus and absent tibia.

De novo direct duplication 7p (p11.2-->pter) in an Arab child with MCA/MR syndrome: trisomy 7p a delineated syndrome?

A 3-year-6-month old Lebanese female child with multiple congenital anomalies including, facial dysmorphism, prominent low set ears, micrognathia, anti-mongoloid palpebral fissures and psychomotor retardation was investigated. Her karyotype showed de novo 46, XX, dir dup (7)(p11.2-->pter). The phenotypic manifestations in dir dup (7p) cases are briefly reviewed. Our observations in combination with other similar cases suggest that 7p trisomy due to dir dup (7p) can be regarded as a defined chromosome syndrome.

Swyer syndrome: an unusual presentation.

We report a 27-year-old XY female who presented with abdominal pain due to hemoperitoneum from a ruptured abdominal mass. Gonadoblastoma overgrown by endodermal sinus tumor and dysgerminoma was detected. The risk of neoplasia in such cases is discussed.

Right upper limb bud triplication and polythelia, left sided hemihypertrophy and congenital hip dislocation, facial dysmorphism, congenital heart disease, and scoliosis: disorganisation-like spectrum or patterning gene defect?

A Somali female baby with right upper limb triplication, polythelia, left sided hemihypertrophy, congenital hip dislocation, facial dysmorphism, congenital heart disease, and scoliosis is described. It seems that the above described pattern of anomalies has not been reported before. The possible developmental genetic mechanism responsible for this phenotype is briefly discussed.
