The majority (88/134; 65.7%) of patients in our cohort declined prenatal diagnosis even in the presence of associated ultrasound findings. Comprehensive pretest and posttest counseling is recommended and should address the importance of confirmatory testing and benefits of early diagnosis. Practice guidelines are needed to address provider responsibilities about postnatal testing.

Objective To describe uptake of carrier screening by male reproductive partners of prenatal and preconception patients. Methods A retrospective database review of all prenatal and preconception patients seen for genetic counseling in Maternal Fetal Medicine clinics was performed. Descriptive statistics and chi‐square analysis were used on the data set. Results Within the study period, 6087 patients were seen for genetic counseling, of whom 661 were identified as a carrier of an autosomal recessive disorder by their referring provider or genetic counselor. Despite guidelines recommending partner testing for risk clarification when a woman is known to be a carrier of an autosomal recessive condition, only 41.5% male partners elected carrier screening to clarify the couple's reproductive risk, with a majority of males (75%) having screening consecutively. Of all assessed variables, the only significant predictors of male carrier screening uptake were female parity and earlier gestational age (p < .0001, and p = .001, respectively). Conclusion With less than half of male partners pursuing carrier screening when indicated, its utility becomes severely diminished. More research is needed to explore reasons why males elect or decline carrier screening.

Objectives Suicide is partly heritable but the responsible genes have not been identified. We conducted a gene-centric, low coverage single nucleotide polymorphism (SNP) pilot genome-wide association study (GWAS) seeking new candidate regions in suicides with and without depression, combined with gene expression assay of brain tissue. Methods Ninety-nine Caucasian subjects, including 68 who completed suicide and 31 who died suddenly from other causes, were genotyped postmortem using GeneChip® Mapping 50K Xba. Clinical data were obtained from relatives. SNPs with Hardy – Weinberg equilibrium P values below 0.001 were excluded from analysis. Illumina chip expression arrays assayed the transcriptome in prefrontal cortex in a drug-free subgroup. Results GWAS analysis (cutoff P < 0.001) yielded 58 SNPs, 22 of them in or near 19 known genes, with risk allele-associated odds ratios between 2.7 and 6.9. Diagnosis of mood disorder did not explain the associations. Some of the SNPs matched into four functional groups in gene ontology. Gene expression in the prefrontal and the anterior cingulate cortex for these 19 genes was measured on a separate, though overlapping, sample of suicides and seven of 19 genes showed altered expression in suicides as compared with controls, especially in immune system related genes. Conclusions Matching GWAS findings with expression data assesses functional effect of new candidate genes in suicide, and is an alternative form of confirmation or replication study. Results highlight a role for neuroimmunological effects in suicidal behaviour.
