Genes affected

RETREG1 (HGNC:25964): (reticulophagy regulator 1) The protein encoded by this gene is a cis-Golgi transmembrane protein that may be necessary for the long-term survival of nociceptive and autonomic ganglion neurons. Mutations in this gene are a cause of hereditary sensory and autonomic neuropathy type IIB (HSAN IIB), and this gene may also play a role in susceptibility to vascular dementia. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]

RETREG1 Gene-Disease associations (from GenCC):

• neuropathy, hereditary sensory and autonomic, type 2B

  Inheritance: AR Classification: DEFINITIVE Submitted by: G2P
• hereditary sensory and autonomic neuropathy type 2

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.326 is higher than 0.05.
