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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PM4

Nonframeshift variant in NON repetitive region in NM_001034850.3. Strenght limited to Supporting due to length of the change: 1aa.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000232 (35/150718) while in subpopulation AFR AF= 0.00083 (34/40978). AF 95% confidence interval is 0.00061. There are 0 homozygotes in gnomad4. There are 17 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.1453_1455delAAG variant (also known as p.K485del) is located in coding exon 9 of the FAM134B gene. This variant results from an in-frame deletion of 3 nucleotides at nucleotide positions 1453 to 1455. This results in an in-frame deletion of a lysine residue at codon 485. This amino acid position is well conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Collection Method: clinical testing

This variant, c.1453_1455del, results in the deletion of 1 amino acid(s) of the RETREG1 protein (p.Lys485del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs758081460, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with RETREG1-related conditions. ClinVar contains an entry for this variant (Variation ID: 439686). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
