Heterozygous variants in PRPF8 are associated with neurodevelopmental disorders.

Area of Science:

• Genetics and Molecular Biology
• Neuroscience
• Ophthalmology

Background:

• The spliceosome component PRPF8 is crucial for pre-mRNA splicing.
• Heterozygous pathogenic variants in PRPF8 are linked to autosomal dominant retinitis pigmentosa.
• PRPF8 variants have been observed in individuals with neurodevelopmental disorders.

Observation:

• Fourteen individuals with neurodevelopmental conditions were identified.
• These individuals carried heterozygous, often de novo, PRPF8 variants.
• The identified variants included missense and loss-of-function types.

Findings:

• A significant association between PRPF8 variants and neurodevelopmental conditions was established.
• The study identified specific clinical features in affected individuals.
• These features may collectively represent a novel neurodevelopmental syndrome.

Implications:

• This research expands the known clinical spectrum associated with PRPF8.
• It highlights PRPF8 as a key gene in neurodevelopmental disorders.
• Further investigation into PRPF8's role could lead to new diagnostic and therapeutic strategies.
