Özet
Treacher Collins syndrome (TCS) is a rare autosomal dominant congenital disorder characterized by various craniofacial malformations. The estimated incidence is 1 in 50000 live births. Bilaterally symmetric anomalies of the structure are present within the first and second branchial arches. Characteristic facial findings includes bilateral hypoplasia of the malar bones and mandible. This syndrome most commonly results from mutations in the TCOF1 gene. Here we present a five-year-old female patient with syndromic appearance and hearing loss. The patient had various facial dysmorphic features and malformed bilateral pinnae and left ear microtia. According to the clinical features, we suspected TCS and sequence analysis of TCOF1 gene was performed. A heterozygous new mutation c. 1722_1731delCATCCTCCAG in exon 12 of the TCOF1 gene was detected. It has been determined that this mutation is pathogenic according to the in silico prediction tools. The current study further expands the TCOF1 mutation spectrum.
