Description

Sequence screening of all the family members showed hemizygous missense mutation (c.877C>G) in POU3F4 gene in both the proband and his mother’s brother . Heterozygous missense mutation (c.877C>G) in POU3F4 gene was found in proband’s mother. No mutations of POU3F4 gene was found in proband’s father and in controls.

Description

The proband and his mother's brother were profound hearing loss since birth , and his mother and father were normal hearing. Then the proband and his mother's brother obtained MRI of inner ear which showed partial cochlear hypoplasia. The genetic analysis showed that the proband and his mother's brother were hemizygous mutation and his mother was carrier of this mutation.
