Abstract
Complete labyrinthine aplasia (CLA) is a rare inner ear anomaly. The only identified genetic cause of CLA with severe sensorineural hearing loss is labyrinthine aplasia, microtia, and microdontia (LAMM) syndrome. Here we reported a child who presented with syndromic hearing loss and was diagnosed with LAMM syndrome. Genetic evaluation provided the family with confirmation of the diagnosis, provision of the prognosis, genetic counselling, and prenatal diagnosis. This report highlighted that CLA should be recognized as a unique sign to diagnose LAMM syndrome, to analyze FGF3 gene mutation, and also demonstrated the utility of genetic testing in patients with suspected LAMM syndrome to provide exact diagnosis and further management.
期刊介绍：
The Journal of Pediatric Genetics is an English multidisciplinary peer-reviewed international journal publishing articles on all aspects of genetics in childhood and of the genetics of experimental models. These topics include clinical genetics, molecular genetics, biochemical genetics, medical genetics, dysmorphology, teratology, genetic counselling, genetic engineering, formal genetics, neuropsychiatric genetics, behavioral genetics, community genetics, cytogenetics, hereditary or syndromic cancer genetics, genetic mapping, reproductive genetics, fetal pathology and prenatal diagnosis, multiple congenital anomaly syndromes, and molecular embryology of birth defects. Journal of Pediatric Genetics provides an in-depth update on new subjects and current comprehensive coverage of the latest techniques used in the diagnosis of childhood genetics. Journal of Pediatric Genetics encourages submissions from all authors throughout the world. The following articles will be considered for publication: editorials, original and review articles, short report, rapid communications, case reports, letters to the editor, and book reviews. The aim of the journal is to share and disseminate knowledge between all disciplines in the field of pediatric genetics. This journal is a publication of the World Pediatric Society: http://www.worldpediatricsociety.org/ The Journal of Pediatric Genetics is available in print and online. Articles published ahead of print are available via the eFirst service on the Thieme E-Journals platform.
