Cayler Cardio-Facial Syndrome: An Uncommon Condition in Newborns

Introduction: Cayler cardio-facial syndrome is a rare syndrome associated with asymmetric crying faces with congenital heart disease. We report a newborn that was diagnosed as case of Cayler Cardio-facial syndrome based on clinical features and was confirmed with FISH analysis. Case Presentation: A term male baby, born to non-consanguineous couple through normal vaginal delivery was diagnosed to have asymmetric crying faces with deviation of angle of mouth to left side at the time of birth. The baby had normal faces while sleeping or silent. Mother was known case of hypothyroidism and was on treatment. Baby was diagnosed as case of Cayler Cardio-facial Syndrome and was investigated with echocardiogram, brain ultrasound, total body X-ray examination, X-ray of cervico-thoracic vertebral column and fundus examination. Echocardiogram showed muscular VSD, brain ultrasound was normal and fundus examination showed tortuous retinal vessels. Whole body X-ray and lateral X-ray of cervico-thoracic vertebral column were not suggestive of any skeletal abnormalities. The other associated malformation was right ear microtia. Baby FISH karyotype analysis showed deletion of 22q11.2 deletion. Baby was discharged and now on follow-up. Conclusions: Cayler syndrome is a rare syndrome which must be suspected if a baby has asymmetrical cry pattern and normal facies when baby sleeps. Patient must be evaluated with echocardiography to find out associated cardiac malformations. These infants should undergo FISH analysis for 22q11.2 deletion syndrome.

Molecular analysis of exons 8, 9 and 10 of the fibroblast growth factor receptor 2 (FGFR2) gene in two families with index cases of Apert Syndrome

Introduction: Apert syndrome (AS) is a craniosynostosis condition caused by mutations in the Fibroblast Growth Factor Receptor 2 (FGFR2) gene. Clinical features include cutaneous and osseous symmetric syndactily in hands and feet, with variable presentations in bones, brain, skin and other internal organs. Methods: Members of two families with an index case of Apert Syndrome were assessed to describe relevant clinical features and molecular analysis (sequencing and amplification) of exons 8, 9 and 10 of FGFR2 gen. Results: Family 1 consists of the mother, the index case and half -brother who has a cleft lip and palate. In this family we found a single FGFR2 mutation, S252W, in the sequence of exon 8. Although mutations were not found in the study of the patient affected with cleft lip and palate, it is known that these diseases share signaling pathways, allowing suspected alterations in shared genes. In the patient of family 2, we found a sequence variant T78.501A located near the splicing site, which could interfere in this process, and consequently with the protein function.
