Genes affected

STIM1 (HGNC:11386): (stromal interaction molecule 1) This gene encodes a type 1 transmembrane protein that mediates Ca2+ influx after depletion of intracellular Ca2+ stores by gating of store-operated Ca2+ influx channels (SOCs). It is one of several genes located in the imprinted gene domain of 11p15.5, an important tumor-suppressor gene region. Alterations in this region have been associated with the Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocrotical carcinoma, and lung, ovarian, and breast cancer. This gene may play a role in malignancies and disease that involve this region, as well as early hematopoiesis, by mediating attachment to stromal cells. Mutations in this gene are associated with fatal classic Kaposi sarcoma, immunodeficiency due to defects in store-operated calcium entry (SOCE) in fibroblasts, ectodermal dysplasia and tubular aggregate myopathy. This gene is oriented in a head-to-tail configuration with the ribonucleotide reductase 1 gene (RRM1), with the 3' end of this gene situated 1.6 kb from the 5' end of the RRM1 gene. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2013]

Variant summary: STIM1 c.1813C>G (p.Pro605Ala) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00048 in 251374 control chromosomes in the gnomAD database (121/251374), including 1 homozygote. To our knowledge, no occurrence of c.1813C>G in individuals affected with STIM1-Related Disorders and no experimental evidence demonstrating its impact on protein function have been reported. STIM1 has been associated with three conditions: Stormorken syndrome is a autosomal dominant condition caused by p.R304W, while Tubular aggregate myopathy is caused by gain-of-function mutation in an autosomal dominant manner and Immunodeficiency 10 is a caused by loss-of-function mutations in an autosomal recessive manner (OMIM, MedGen). The relatively high frequency in controls, including the homozgyous occurrence is strong evidence that the variant is benign for the conditions caused by this gene. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as likely benign. -
