Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 1P and 9B. PP2BP4_StrongBP6BS2

The NM_015915.5(ATL1):c.27C>G(p.Asn9Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000359 in 1,613,894 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N9S) 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]

ATL1 links:

MAP4K5 (HGNC:6867): (mitogen-activated protein kinase kinase kinase kinase 5) This gene encodes a member of the serine/threonine protein kinase family, that is highly similar to yeast SPS1/STE20 kinase. Yeast SPS1/STE20 functions near the beginning of the MAP kinase signal cascades that is essential for yeast pheromone response. This kinase was shown to activate Jun kinase in mammalian cells, which suggested a role in stress response. Two alternatively spliced transcript variants encoding the same protein have been described for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 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=0.05847168).

BP6

Variant 14-50560292-C-G is Benign according to our data. Variant chr14-50560292-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 538580.

BS2

High AC in GnomAd4 at 6 AD,SD gene.
