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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2022The c.730C>G (p.P244A) alteration is located in exon 4 (coding exon 4) of the VSIG4 gene. This alteration results from a C to G substitution at nucleotide position 730, causing the proline (P) at amino acid position 244 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
