Syndromic Hearing Loss in Association with PTPN11-Related Disorder: The Experience of Cochlear Implantation in a Child with LEOPARD Syndrome

Hearing loss (HL) is one of the most frequent clinical manifestations of patients who suffer with multi-systemic genetic disorders. HL in association with other physical stigmata is referred to as a syndromic form of HL. LEOPARD syndrome (LS) is one of the disorders with syndromic HL and it is cause...

description Hearing loss (HL) is one of the most frequent clinical manifestations of patients who suffer with multi-systemic genetic disorders. HL in association with other physical stigmata is referred to as a syndromic form of HL. LEOPARD syndrome (LS) is one of the disorders with syndromic HL and it is caused by a mutation in the PTPN11 or RAF1 gene. In general, 5 year old children who undergo cochlear implantation usually show a marked change in behavior regarding sound detection within the first 6 months of implant use, but word identification may not be exhibited for at least another 6-12 months of implant use. We herein report on a 5-year-old girl with LS. Her clinical manifestations including bilateral sensorineural HL, which indicated the diagnosis of LS. We confirmed the diagnosis by identifying a disease-causing mutation in the PTPN11 gene, which was a heterozygous missense mutation Ala461Thr (c.1381G>A). She underwent cochlear implantation (CI) without complications and she is currently on regular follow-up at postoperative 1 year. This is the first reported case of CI in a patient with LS in the medical literature.
