Genes affected

TOR1AIP1 (HGNC:29456): (torsin 1A interacting protein 1) This gene encodes a type 2 integral membrane protein that binds A- and B-type lamins. The encoded protein localizes to the inner nuclear membrane and may be involved in maintaining the attachment of the nuclear membrane to the nuclear lamina during cell division. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Apr 2016]

TOR1AIP1 links:

TOR1AIP2 (HGNC:24055): (torsin 1A interacting protein 2) One of the two protein isoforms encoded by this gene is a type II integral membrane protein found in the endoplasmic reticulum (ER). The encoded protein is a cofactor for the ATPase TorsinA, regulating the amount of TorsinA present in the ER compared to that found in the nuclear envelope. Defects in this protein are a cause of early onset primary dystonia, a neuromuscular disease. The other isoform encoded by this gene is an interferon alpha responsive protein whose cellular role has yet to be determined. [provided by RefSeq, Mar 2017]

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (MetaRNN=0.12155804).

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000177 (259/1461894) while in subpopulation NFE AF = 0.00023 (256/1112012). AF 95% confidence interval is 0.000207. There are 0 homozygotes in GnomAdExome4. There are 112 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
