Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2 PP2 PP3

The NM_003061.3(SLIT1):​c.131C>T​(p.Thr44Met) variant causes a missense change. The variant allele was found at a frequency of 0.00000124 in 1,611,752 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T44K) has been classified as Uncertain significance.

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]

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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 3.0887 (below the threshold of 3.09). Trascript score misZ: 3.2604 (above the threshold of 3.09).
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.834
