Genes affected
ATL1 (HGNC:11231): (atlastin GTPase 1) The protein encoded by this gene is a GTPase and a Golgi body transmembrane protein. The encoded protein can form a homotetramer and has been shown to interact with spastin and with mitogen-activated protein kinase kinase kinase kinase 4. This protein may be involved in axonal maintenance as evidenced by the fact that defects in this gene are a cause of spastic paraplegia type 3. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the ATL1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 60 curated pathogenic missense variants (we use a threshold of 10). The gene has 10 curated benign missense variants. Gene score misZ: 2.6313 (below the threshold of 3.09). Trascript score misZ: 3.8383 (above the threshold of 3.09). GenCC associations: The gene is linked to hereditary sensory and autonomic neuropathy type 1, hereditary spastic paraplegia 3A, neuropathy, hereditary sensory, type 1D.
BP4
Computational evidence support a benign effect (MetaRNN=0.29526293).
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000722 (11/152294) while in subpopulation AFR AF= 0.000144 (6/41578). AF 95% confidence interval is 0.0000627. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

Hereditary spastic paraplegia 3A Uncertain:1
Sep 11, 2024
Labcorp Genetics (formerly Invitae), Labcorp
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 405 of the ATL1 protein (p.Val405Met). This variant is present in population databases (rs201240362, gnomAD 0.008%). This missense change has been observed in individual(s) with autosomal dominant hereditary spastic paraplegia (PMID: 31594988). ClinVar contains an entry for this variant (Variation ID: 471245). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ATL1 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
