Neuroscience 2024; 544:128-137. [PMID: 38447690 PMCID: PMC11146016 DOI: 10.1016/j.neuroscience.2024.02.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 02/09/2024] [Accepted: 02/28/2024] [Indexed: 03/08/2024]
Abstract
In Robo3cKO mice, midline crossing defects of the trigeminothalamic projections from the trigeminal principal sensory nucleus result in bilateral whisker maps in the somatosensory thalamus and consequently in the face representation area of the primary somatosensory (S1) cortex (Renier et al., 2017; Tsytsarev et al., 2017). We investigated whether this bilateral sensory representation in the whisker-barrel cortex is also reflected in the downstream projections from the S1 to the primary motor (M1) cortex. To label these projections, we injected anterograde viral axonal tracer in S1 cortex. Corticocortical projections from the S1 distribute to similar areas across the ipsilateral hemisphere in control and Robo3cKO mice. Namely, in both genotypes they extend to the M1, premotor/prefrontal cortex (PMPF), secondary somatosensory (S2) cortex. Next, we performed voltage-sensitive dye imaging (VSDi) in the left hemisphere following ipsilateral and contralateral single whisker stimulation. While controls showed only activation in the contralateral whisker barrel cortex and M1 cortex, the Robo3cKO mouse left hemisphere was activated bilaterally in both the barrel cortex and the M1 cortex. We conclude that the midline crossing defect of the trigeminothalamic projections leads to bilateral whisker representations not only in the thalamus and the S1 cortex but also downstream from the S1, in the M1 cortex.

Abstract
PURPOSE This study is to describe the special clinical and genotypic features of a Chinese family with variant types of Duane retraction syndrome and to present our experience on managing these cases. METHODS Four individuals from one family were reviewed by ophthalmologic examinations, in which two affected and two unaffected individuals were revealed. MRI scans were performed on the two patients. Relevant gene mutations were screened by the next-generation sequencing technology and confirmed by Sanger sequencing technology. RESULTS The six-year-old proband presented with special clinical features of severe horizontal gaze dysfunction, exotropia and mild scoliosis. His mother showed significantly limited binocular abductions, with retraction of eyeballs in adduction. From MRI scans, abducens nerves were not observed in both patients and the oculomotor nerve was slightly thin in the proband. The proband and his mother shared the same CHN1 gene mutation site (c. 62A>G; p.Y21C). Strabismus surgery was performed on the proband to correct the primary gaze exotropia.(NM_001822: exon3 or NM_001025201: exon4: c. 62A>G; p.Y21C). CONCLUSIONS A novel CHN1 gene mutation was revealed from a Chinese family with Duane retraction syndrome. Remarkably, the proband and his mother presented different clinical features of ocular motility disorder. Strabismus correction surgery and amblyopia training helped to improve the appearance and visual function of the proband.

Early onset horizontal gaze palsy and progressive scoliosis due to a noncanonical splicing-site variant and a missense variant in the ROBO3 gene. Mol Genet Genomic Med 2023; 11:e2215. [PMID: 37330975 PMCID: PMC10496041 DOI: 10.1002/mgg3.2215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Revised: 05/10/2023] [Accepted: 05/23/2023] [Indexed: 06/20/2023] Open
Abstract
BACKGROUND Homozygous or compound heterozygous ROBO3 gene mutations cause horizontal gaze palsy with progressive scoliosis (HGPPS). This is an autosomal recessive disorder that is characterized by congenital absence or severe restriction of horizontal gaze and progressive scoliosis. To date, almost 100 patients with HGPPS have been reported and 55 ROBO3 mutations have been identified. METHODS We described an HGPPS patient and performed whole-exome sequencing (WES) to identify the causative gene. RESULTS We identified a missense variant and a splice-site variant in the ROBO3 gene in the proband. Sanger sequencing of cDNA revealed the presence of an aberrant transcript with retention of 700 bp from intron 17, which was caused by a variation in the noncanonical splicing site. We identified five additional ROBO3 variants, which were likely pathogenic, and estimated the overall allele frequency in the southern Chinese population to be 9.44 × 10-4 , by a review of our in-house database. CONCLUSION This study has broadened the mutation spectrum of the ROBO3 gene and has expanded our knowledge of variants in noncanonical splicing sites. The results could help to provide more accurate genetic counseling to affected families and prospective couples. We suggest that the ROBO3 gene should be included in the local screening strategy.

Horizontal Gaze Palsy with Progressive Scoliosis with Overlapping Epilepsy and Learning Difficulties: A Case Report. Brain Sci 2022; 12:brainsci12050613.

Abstract
Horizontal gaze palsy with progressive scoliosis (HGPPS) is a rare congenital disease characterized by the absence of horizontal gaze movements, progressive scoliosis, and typical brain, cerebellum, and medullary malformations. Here we describe a pediatric HGPPS case with overlapping epilepsy and learning difficulties. A 6-year-old girl was admitted to the University Hospital of Bari for the onset of a tonic–clonic seizure. Electroencephalogram showed slow and sharp waves on the right side with the tendency to diffuse. Brain magnetic resonance imaging demonstrated malformations compatible with HGPPS. Ophthalmological and orthopedic evaluations confirmed conjugate horizontal gaze palsy and mild thoracolumbar scoliosis. Neuropsychological assessment attested normal intelligence but serious difficulties in reading and writing. In spite of neuroradiological malformations, visual difficulties, and spinal deformities, literature data are limited about any coexisting neurocognitive HGPPS symptoms. Literature data regarding such topics are very limited. If, on the one hand, the coexistence of such symptoms can be interpreted as occasional, it could support the idea that they could fall within a spectrum of HGPPS anomalies. In addition to the standard investigations, the activation of specific neuropsychological assessment programs could help interventions improve the specialist care and the quality of life of HGPPS patients.

Abstract
Horizontal gaze palsy with progressive scoliosis (HGPPS) is an autosomal recessive disorder caused by ROBO3 gene mutations. To date, the number of confirmed HGPPS cases caused by gene mutations is estimated at 76. However, HGPPS caused by ROBO3 gene mutation has not been reported in the Chinese population. In this study, the clinical data, brain imaging features, somatosensory evoked potentials (SEP), and ROBO3 gene mutations were obtained for two Chinese patients with HGPPS. The proband was an 11-year-old boy. He developed horizontal eye movement disorder at the age of 1 year and scoliosis at the age of 11 years. Two eyeballs fixed in the midline position were revealed by neurological examination. A dorsal cleft in the pons and a butterfly-shaped medulla were shown by brain magnetic resonance imaging. Again, most corticospinal bundles did not cross in the brainstem, as revealed by diffusion tensor imaging. SEP confirmed that most somatosensory projections were uncrossed. The proband's 7-year-old brother exhibited similar clinical manifestations and imaging features. The brothers had compound heterozygous mutations c.3165G>A (p.W1055X) and c.955G>A (p.E319K) of the ROBO3 gene. The c.3165G>A mutation is a novel nonsense mutation that has not been previously reported. This study reports the first two cases of HGPPS carrying a novel ROBO3 gene mutation in patients from a Chinese family, thereby expanding the disease spectrum. Reports from the literature show that missense mutation is the most common mutational type in the ROBO3 gene. Early ROBO3 gene detection is required for patients exhibiting early-onset eyeball movement disorder to confirm HGPPS disease.

Mutation in ROBO3 Gene in Patients with Horizontal Gaze Palsy with Progressive Scoliosis Syndrome: A Systematic Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E4467.

Abstract
Horizontal gaze palsy with progressive scoliosis (HGPPS) is a rare, inherited disorder characterized by a congenital absence of conjugate horizontal eye movements with progressive scoliosis developing in childhood and adolescence. Mutations in the Roundabout (ROBO3) gene located on chromosome 11q23-25 are responsible for the development of horizontal gaze palsy and progressive scoliosis. However, some studies redefined the locus responsible for this pathology to a 9-cM region. This study carried out a systematic review in which 25 documents were analyzed, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. The search was made in the following electronic databases from January 1995 to October 2019: PubMed, Scopus, Web of Science, PEDRO, SPORT Discus, and CINAHL. HGPPS requires a multidisciplinary diagnostic approach, in which magnetic resonance imaging might be the first technique to suggest the diagnosis, which should be verified by an analysis of the ROBO3 gene. This is important to allow for adequate ocular follow up, apply supportive therapies to prevent the rapid progression of scoliosis, and lead to appropriate genetic counseling.
