婴幼儿中引起严重的感音神经性聋(SN-HL)最常见的原因是遗传,大约40%病例由基因突变所致。在所有遗传性SNHL病例中常染色体隐性型的遗传约占70%或更多。儿童的双亲有常染色体隐性SNHL将携带引起耳聋的特殊基因,同胞儿童都有1/4类似的患病机会。潜在表现的常染色体隐性SNHL在听力损伤儿童
The most common cause of severe sensorineural deafness (SN-HL) in infants and young children is heredity and about 40% of cases are caused by genetic mutations. Autosomal recessive inheritance accounts for about 70% or more in all cases of inherited SNHL. Children with autosomal recessive SNHL parents will carry a special gene that causes deafness, Sibu children have a similar 1/4 chance of illness. Potential manifestations of autosomal recessive SNHL in hearing-impaired children
