A novel Nance-Horan syndrome mutation identified by next-generation sequencing in a Chinese family.

ABSTRACT:

Aim

To identify the disease-causing mutation in a four-generation Chinese family diagnosed with Nance-Horan syndrome (NHS).

Methods

A Chinese family, including four affected patients and four healthy siblings, was recruited. All family members received ophthalmic examinations with medical histories provided. Targeted next-generation sequencing approach was conducted on the two affected males to screen for their disease-causing mutations.

Results

Two male family members diagnosed with NHS manifested bilateral congenital cataracts microcornea, strabismus and subtle facial and dental abnormalities, while female carriers presented posterior Y-sutural cataracts. A novel frameshift mutation (c.3916_3919del) in the NHS gene was identified. This deletion was predicted to alte
