Genes affected

ERVV-2 (HGNC:39051): (endogenous retrovirus group V member 2, envelope) Many different human endogenous retrovirus (HERV) families are expressed in normal placental tissue at high levels, suggesting that HERVs are functionally important in reproduction. This gene is part of an HERV provirus on human chromosome 19 that has inactivating mutations in the gag and pol genes. This envelope glycoprotein gene appears to have been selectively preserved. The gene's protein product is expressed in the placenta and acts as a syncytin in Old World monkeys, but has lost the fusogenic activity in humans and other primate lineages.

The c.1039G>A (p.V347I) alteration is located in exon 2 (coding exon 1) of the ERVV-2 gene. This alteration results from a G to A substitution at nucleotide position 1039, causing the valine (V) at amino acid position 347 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
