Genes affected
VSIG4 (HGNC:17032): (V-set and immunoglobulin domain containing 4) This gene encodes a v-set and immunoglobulin-domain containing protein that is structurally related to the B7 family of immune regulatory proteins. The encoded protein may be a negative regulator of T-cell responses. This protein is also a receptor for the complement component 3 fragments C3b and iC3b. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.1132G>A (p.A378T) alteration is located in exon 8 (coding exon 8) of the VSIG4 gene. This alteration results from a G to A substitution at nucleotide position 1132, causing the alanine (A) at amino acid position 378 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
