Deficiency of FRMD5 results in neurodevelopmental dysfunction and autistic-like behavior in mice. Mol Psychiatry 2024:10.1038/s41380-024-02407-w. [PMID: 38228891 DOI: 10.1038/s41380-024-02407-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 12/17/2023] [Accepted: 01/02/2024] [Indexed: 01/18/2024]
Abstract
The pathophysiology of autism spectrum disorders (ASDs) is causally linked to postsynaptic scaffolding proteins, as evidenced by numerous large-scale genomic studies [1, 2] and in vitro and in vivo neurobiological studies of mutations in animal models [3, 4]. However, due to the distinct phenotypic and genetic heterogeneity observed in ASD patients, individual mutation genes account for only a small proportion (<2%) of cases [1, 5]. Recently, a human genetic study revealed a correlation between de novo variants in FERM domain-containing-5 (FRMD5) and neurodevelopmental abnormalities [6]. In this study, we demonstrate that deficiency of the scaffolding protein FRMD5 leads to neurodevelopmental dysfunction and ASD-like behavior in mice. FRMD5 deficiency results in morphological abnormalities in neurons and synaptic dysfunction in mice. Frmd5-deficient mice display learning and memory dysfunction, impaired social function, and increased repetitive stereotyped behavior. Mechanistically, tandem mass tag (TMT)-labeled quantitative proteomics revealed that FRMD5 deletion affects the distribution of synaptic proteins involved in the pathological process of ASD. Collectively, our findings delineate the critical role of FRMD5 in neurodevelopment and ASD pathophysiology, suggesting potential therapeutic implications for the treatment of ASD.

Abstract
The function of some genetic variants associated with brain-relevant traits has been explained through colocalization with expression quantitative trait loci (eQTL) conducted in bulk post-mortem adult brain tissue. However, many brain-trait associated loci have unknown cellular or molecular function. These genetic variants may exert context-specific function on different molecular phenotypes including post-transcriptional changes. Here, we identified genetic regulation of RNA-editing and alternative polyadenylation (APA), within a cell-type-specific population of human neural progenitors and neurons. More RNA-editing and isoforms utilizing longer polyadenylation sequences were observed in neurons, likely due to higher expression of genes encoding the proteins mediating these post-transcriptional events. We also detected hundreds of cell-type-specific editing quantitative trait loci (edQTLs) and alternative polyadenylation QTLs (apaQTLs). We found colocalizations of a neuron edQTL in CCDC88A with educational attainment and a progenitor apaQTL in EP300 with schizophrenia, suggesting genetically mediated post-transcriptional regulation during brain development lead to differences in brain function.

Badv RS, Mahdiannasser M, Rasoulinezhad M, Habibi L, Rashidi-Nezhad A. CEP104 gene may involve in the pathogenesis of a new developmental disorder other than joubert syndrome. Mol Biol Rep 2022; 49:7231-7237. [PMID: 35359234 DOI: 10.1007/s11033-022-07353-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Accepted: 03/09/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND The CEP104 gene (OMIM: 616,690) encodes the centrosome protein 104 (CEP104) that is involved in cilia function. Pathogenic variants in this gene have been described in four patients diagnosed with Joubert syndrome (JBTS) 25. Here, we challenged the concept that pathogenic variants in CEP104 gene are only involved in the development of JBTS 25. METHODS AND RESULTS In a clinical setting, whole-exome sequencing (WES) was applied to investigate pathogenic variants in patients with unexplained developmental delay or intellectual disability (DD/ID).WES revealed a novel homozygous nonsense variant (c.643C > T) in CEP104 (NM _014704.3) in a girl with mild intellectual disability, hypotonia, and imbalanced gait. Her brain MRI data did not show molar tooth sign (MTS) or any other brain anomalies. CONCLUSION Our study introduced a novel variant in the CEP104 gene that results in an ID phenotype other than JBTS25. Comparison of her phenotype with that of eight previously published DD/ID patients harboring pathogenic variants in CEP104 gene revealed that more than half of them did not show JBTS related symptoms. Therefore, we suggest that the CEP104 gene might also be involved in a disorder other than JBTS 25, a point that deserves to be emerged in the OMIM database.
