Variant summary
Our verdict is Pathogenic. Variant got 13 ACMG points: 13P and 0B. PM1PM2PM5PP2PP3_StrongPP5_Moderate
The NM_015915.5(ATL1):c.1193C>A(p.Ser398Tyr) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S398F) 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]

Hereditary spastic paraplegia 3A Pathogenic:1Uncertain:1
Uncertain significance, no assertion criteria provided | literature only | Inherited Neuropathy Consortium Ii, University Of Miami | Jan 06, 2016 | - - |
Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 06, 2015 | For these reasons, this variant has been classified as Likely Pathogenic. A different missense substitution at this codon (p.Ser398Phe) is reported to be deleterious (PMID: 19735987). This suggests that the serine residue is important for ATL1 protein function. This variant has been reported in the literature and is not present in population databases. This variant was reported in an individual affected with autosomal dominant hereditary spastic paraplegia, although it is unclear if this variant segregated with disease (PMID: 15596607). This sequence change replaces serine with tyrosine at codon 398 of the ATL1 protein (p.Ser398Tyr). The serine residue is moderately conserved and there is a large physicochemical difference between serine and tyrosine. - |
