Genetic Variant RETREG1:c.*71_*72insAAACACAAAAAAAATTTAAAAAAAAAAAAAAAAAAAAAAAAA (chr5-16474669-C-CTTTTTTTTTTTTTTTTTTTTTTTTTAAATTTTTTTTGTGTTT) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_001034850.3(RETREG1):c.*71_*72insAAACACAAAAAAAATTTAAAAAAAAAAAAAAAAAAAAAAAAA variant causes a 3 prime UTR change involving the alteration of a non-conserved nucleotide. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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]
