Genes affected
VSIG1 (HGNC:28675): (V-set and immunoglobulin domain containing 1) This gene encodes a member of the junctional adhesion molecule (JAM) family. The encoded protein contains multiple glycosylation sites at the N-terminal region, and multiple phosphorylation sites and glutamic acid/proline (EP) repeats at the C-terminal region. The gene is expressed in normal stomach and testis, as well as in gastric, esophageal and ovarian cancers. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2022The c.929C>T (p.A310V) alteration is located in exon 7 (coding exon 7) of the VSIG1 gene. This alteration results from a C to T substitution at nucleotide position 929, causing the alanine (A) at amino acid position 310 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
