Genes affected

SLIT1 (HGNC:11085): (slit guidance ligand 1) Enables Roundabout binding activity. Involved in axon extension involved in axon guidance; motor neuron axon guidance; and negative chemotaxis. Predicted to be located in extracellular region. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

SLIT1 links:

ARHGAP19-SLIT1 (HGNC:48348): (ARHGAP19-SLIT1 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring Rho GTPase activating protein 19 (ARHGAP19) and slit homolog 1 (SLIT1) genes on chromosome 10. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]

Collection Method: clinical testing

The c.288G>C (p.Q96H) alteration is located in exon 3 (coding exon 3) of the SLIT1 gene. This alteration results from a G to C substitution at nucleotide position 288, causing the glutamine (Q) at amino acid position 96 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
