Variant summary

Our verdict is Benign. The variant received -19 ACMG points: 1P and 20B. PP2BP4_StrongBP6_Very_StrongBS1BS2

The NM_015915.5(ATL1):​c.306C>A​(p.Asp102Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000855 in 1,613,834 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D102H) has been classified as Uncertain significance.

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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -19 ACMG points.

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 spastic paraplegia 3A, neuropathy, hereditary sensory, type 1D, hereditary sensory and autonomic neuropathy type 1.
BP4
Computational evidence support a benign effect (MetaRNN=0.011648834).
BP6
Variant 14-50590964-C-A is Benign according to our data. Variant chr14-50590964-C-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 538585.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
