Genes affected

PPP3R2 (HGNC:9318): (protein phosphatase 3 regulatory subunit B, beta) Predicted to enable calcium ion binding activity and calcium-dependent protein serine/threonine phosphatase regulator activity. Predicted to be involved in regulation of catalytic activity. Predicted to act upstream of or within penetration of zona pellucida. Predicted to be located in sperm mitochondrial sheath. Predicted to be part of calcineurin complex. [provided by Alliance of Genome Resources, Apr 2022]

GRIN3A (HGNC:16767): (glutamate ionotropic receptor NMDA type subunit 3A) This gene encodes a subunit of the N-methyl-D-aspartate (NMDA) receptors, which belong to the superfamily of glutamate-regulated ion channels, and function in physiological and pathological processes in the central nervous system. This subunit shows greater than 90% identity to the corresponding subunit in rat. Studies in the knockout mouse deficient in this subunit suggest that this gene may be involved in the development of synaptic elements by modulating NMDA receptor activity.
