NLRP7

A gene located on chromosome 19q13.42 that encodes a member of the NACHT protein family, which is thought to act as a feedback regulator, inhibiting caspase-1-dependent interleukin 1-beta secretion.

Our findings are in concordance with those of Deveault et al, (26) who demonstrated that NLRP7 mutations or variants are responsible not only for diploid biparental moles as previously shown, but also for diploid androgenetic moles, triploid moles, and for tetraploid spontaneous abortions.
