Introduction Recently, You, Hoover-Fong, and colleagues described a disease caused by a deficiency of the telomere maintenance 2 gene (TELO2) function. The clinical spectrum includes early-onset global delay, dysmorphic facial features, auditory disorder, and reduced vision. Materials and methods We report two siblings, diagnosed with You-Hoover-Fong syndrome at the age of 28 and 14 months. Both were genetically studied to find the cause of their developmental delay and microcephaly. Results The identical compound heterozygous missense mutations in theTELO2gene were found in each. Ophthalmologically, both siblings were diagnosed with progressive congenital bilateral nuclear-lamellar cataracts. Conclusions We report nuclear-lamellar cataracts in two siblings diagnosed with You-Hoover-Fong syndrome.
