Abstract EN
Hearing loss is one of the most common sensory disorders in newborns and is mostly caused by genetic factors.
Autosomal recessive nonsyndromic hearing loss (ARNSHL) is usually characterized as a severe-to-profound congenital sensorineural hearing loss and later can cause various degrees of defect in the language and intelligent development of newborns.
The mutations in LOXHD1 gene have been shown to cause DFNB77, a type of ARNSHL.
To date, there are limited reports about the association between LOXHD1 gene and ARNSHL.
In this study, we reported six patients from four Chinese families suffering from severe-to-profound nonsyndromic hearing loss.
We performed targeted next generation sequencing in the six affected members and identified five novel pathogenic mutations in LOXHD1 including c.277G>A (p.D93N), c.611-2A>T, c.1255+3A>G, c.2329C>T (p.Q777∗), and c.5888delG (p.G1963Afs∗136).
These mutations were confirmed to be cosegregated with the hearing impairment in the families by Sanger sequencing and were inherited in an autosomal recessive pattern.
All of the five mutations were absent in 200 control subjects.
There were no symptoms of Fuchs corneal dystrophy in the probands and their blood-related relatives.
We concluded that these five novel mutations could be involved in the underlying mechanism resulting in the hearing loss, and this discovery expands the genotypic spectrum of LOXHD1 mutations.
