Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the ROBO3 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Thought to be involved during neural development in axonal navigation at the ventral midline of the neural tube. In spinal chord development plays a role in guiding commissural axons probably by preventing premature sensitivity to Slit proteins thus inhibiting Slit signaling through ROBO1 (By similarity). Required for hindbrain axon midline crossing. {ECO:0000250, ECO:0000269|PubMed:15105459}.
• Disease: DISEASE: Gaze palsy, familial horizontal, with progressive scoliosis, 1 (HGPPS1) [MIM:607313]: An autosomal recessive neurologic disorder characterized by eye movement abnormalities apparent from birth, childhood-onset progressive scoliosis, distinctive brainstem malformation and defective crossing of some brainstem neuronal pathways. {ECO:0000269|PubMed:15105459}. Note=The disease is caused by mutations affecting the gene represented in this entry.
