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.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.557T>C (p.L186P) alteration is located in exon 5 (coding exon 5) of the ATL3 gene. This alteration results from a T to C substitution at nucleotide position 557, causing the leucine (L) at amino acid position 186 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
