“…DNMs, defi ned as mutations arising sporadically either in the germ-line of the parents or at an early stage of embryonic development so that the mutations are only detected in affected individual but not in the parents, was proposed many years ago as a mechanism to offset the negative selection [68] . This proposition was based on the epidemiological observation that paternal age is associated with an increased risk of SCZ [69][70][71] . This hypothesis did not receive much attention in genetic studies until recently, when high-throughput DNA sequencing of SCZ families provided direct evidence that affected offspring have excess DNMs across the genome [72,73] .…”

“…Plusieurs études ont montré que l"âge maternel n"est pas associé à une augmentation du risque de schizophrénie [2,5,18,34,37,38,42]. Néanmoins, Byrne et al, [3] mettent en évidence une augmentation du risque de schizophrénie, lorsque la mère a plus de 40 ans, après ajustement sur l"âge paternel et l"existence d"antécédents psychiatriques familiaux, mais cette corrélation disparaît après ajustement sur les facteurs socio-économiques. Une autre étude [6] retrouve une influence de l"âge maternel (RR=1,4 pour les mères de plus de 34 ans), après ajustement sur l"âge paternel, toutefois dans cette étude, l"influence de l"âge de la mère semble moindre en comparaison à celle de l"âge paternel (RR=2).…”

“…Des résultats contradictoires sont retrouvés concernant l"influence du sexe du sujet atteint [3,18,34]. Par exemple, Malaspina et al, [18] mettent en évidence un risque plus élevé chez les garçons (risque multiplié par 1,4 par tranche de 10 ans d"âge paternel contre 1,26 chez les filles), mais ce résultat n"est pas confirmé par d"autres études [34].…”
