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]

ATL1 links:

SAV1 (HGNC:17795): (salvador family WW domain containing protein 1) WW domain-containing proteins are found in all eukaryotes and play an important role in the regulation of a wide variety of cellular functions such as protein degradation, transcription, and RNA splicing. This gene encodes a protein with two WW domains, a SARAH domain, and a coiled-coil region and is ubiquitously expressed in adult tissues. This protein binds to MST1 (mammalian sterile 20-like kinase 1) and promotes MST1-induced apoptosis. It has also been shown to bind to HAX1 (hematopoietic cell-specific protein 1 (HS1)-associated protein X-1) and to attenuate the anti-apoptotic effects of HAX1. Studies in human and mouse suggest this gene acts as a tumor suppressor. [provided by RefSeq, Aug 2012]

The p.Y538N variant (also known as c.1612T>A), located in coding exon 14 of the ATL1 gene, results from a T to A substitution at nucleotide position 1612. The tyrosine at codon 538 is replaced by asparagine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the supporting evidence, this variant is unlikely to be causative of autosomal dominant spastic paraplegia 3A (SPG3A) or hereditary sensory neuropathy type ID (HSN1D); however, its contribution to the development of autosomal recessive spastic paraplegia 3A is uncertain. -

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ATL1 protein function. ClinVar contains an entry for this variant (Variation ID: 1776429). This variant has not been reported in the literature in individuals affected with ATL1-related conditions. This variant is present in population databases (rs200185276, gnomAD 0.04%). This sequence change replaces tyrosine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 538 of the ATL1 protein (p.Tyr538Asn). -
