This systematic review analyzed genetic associations with gastroschisis from 1980-2017, identifying 14 SNPs from 10 genes associated with crude risk and 30 SNPs from 14 genes with stratified risk. Four SNPs showed significant associations: rs4961 (ADD1, p=0.023), rs5443 (GNB3, p=0.002), rs1042713 (ADRB2, p=0.007), and rs1042714 (ADRB2, p=0.006). The findings suggest genetic susceptibility in gastroschisis is not restricted to gene-environment interactions, with blood pressure regulation genes playing a significant role in vascular disruption pathogenesis.

Two-stage replication study of 9 SNPs in 8 genes previously associated with breast cancer survival in 6,307 Chinese women (Stage 1: 1,115 cases, Stage 2: 5,192 cases). MMP7 rs11225297 and MMP8 rs11225395 showed consistent associations with overall survival, with rare alleles conferring 20-40% improved survival (HR 0.4-0.6 and 0.6 for TT genotypes respectively, p<0.001).

This journal issue contains multiple genetic association studies on rheumatoid arthritis (RA). A key REMARCA study (146 aCCP+ RA patients vs 314 controls) identified polymorphisms in CTLA4 (rs231775 +49A/G), IL10 (rs1800872 -592A/C), and IL6R (rs8192284 +358A/C) associated with high inflammatory disease activity, with CTLA4 and IL10 minor alleles showing increased risk (OR=1.4, p=0.02 and OR=1.9, p<0.0001 respectively) and IL6R minor allele being protective (OR=0.7, p=0.03). A separate study analyzed NOS3, PPARG, PPARGC1A, PPARGC1B and PAI1 polymorphisms in 73 RA patients for cardiovascular risk.
