Introduction: Recently, You, Hoover-Fong, and colleagues described a disease caused by a deficiency of the telomere maintenance 2 gene () 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 the gene 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.

You-Hoover-Fong syndrome (YHFS) is a rare autosomal recessive disorder characterized by global developmental delay, microcephaly, dysmorphic facial features, and a spectrum of neurodevelopmental abnormalities. YHFS is caused by pathogenic variants in TELO2, a gene involved in regulation of the cell cycle. To date, 29 individuals with YHFS have been reported and none of them has been reported to develop tumors.

Background: The ultra-rare autosomal recessive genetic disorder, You-Hoover-Fong Syndrome (YHFS), is caused by defects in the TELO2 gene and is characterized by intellectual disability, developmental delay, and ocular impairments. This study aims to contribute to a better understanding of YHFS by reviewing previous cases and introducing a novel variant in a new case.

Methods: Whole exome sequencing (WES) was conducted on the proband to identify genetic variants, and Sanger sequencing was used to confirm variants within the family.

We report here the clinical diagnosis and treatment and genetic mutations of an infant with You-Hoover-Fong syndrome (YHFS). The relevant literature review was conducted. A female infant aged 17 months was admitted to Nanhai Affiliated Maternity and Children's Hospital of Guangzhou University of Chinese Medicine due to "global development delay complicated with postnatal growth retardation for more than 1 year.

You-Hoover-Fong syndrome (YHFS) is an autosomal recessive condition caused by pathogenic variants in the TELO2 gene. Affected individuals were reported to have global developmental delay, intellectual disability, microcephaly, dysmorphic facial features, ocular involvement including cortical visual impairment, strabismus, cataract and rotatory nystagmus, movement disorder, hypertonia and spasticity, balance disturbance and ataxia, and abnormal sleep pattern. Other features reported include poor growth, cleft palate, cardiac malformations, epilepsy, scoliosis, and hearing loss.

Nonsense-mediated mRNA decay (NMD) controls eukaryotic mRNA quality, inducing the degradation of faulty transcripts. Key players in the NMD pathway were originally identified, through genetics, in Caenorhabditis elegans as smg (suppressor with morphological effect on genitalia) genes. Using forward genetics and fluorescence-based NMD reporters, we reexamined the genetic landscape underlying NMD.
