Genes affected

ATL3 (HGNC:24526): (atlastin GTPase 3) This gene encodes a member of a family of dynamin-like, integral membrane GTPases. The encoded protein is required for the proper formation of the network of interconnected tubules of the endoplasmic reticulum. Mutations in this gene may be associated with hereditary sensory neuropathy type IF. Alternatively spliced transcript variants that encode distinct isoforms have been described.

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BS2: High AC in GnomAdExome4 at 30 AD gene.

This sequence change falls in intron 11 of the ATL3 gene. It does not directly change the encoded amino acid sequence of the ATL3 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs369978511, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with ATL3-related conditions. ClinVar contains an entry for this variant (Variation ID: 541676). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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. -
