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.

ATL3 Gene-Disease associations (from GenCC):

• neuropathy, hereditary sensory, type 1F

  Inheritance: AD Classification: STRONG, MODERATE Submitted by: Ambry Genetics, ClinGen, Labcorp Genetics (formerly Invitae)
• hereditary sensory and autonomic neuropathy type 1

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

LNCROPM (HGNC:58146):

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.59).
• BP7: Synonymous conserved (PhyloP=1.64 with no splicing effect.
