Whole-genomesequencing offers a more comprehensive prenatal test
Although WGS is a suitable method for identifying fetal CNS anomalies, our approach has some limitations. Firstly, triploids were not analyzed in this study. Furthermore, due to the lack of large-scale databases, it was difficult to determine the clinical significance of variants in introns and noncoding areas.
. To be simplified, approximately of 200 mg tissue was diced and homogenated with 2 ml of lysis buffer. Then the tissue lysates were incubated at 65°C with 0.2 ml of 10% SDS and 0.5 ml of a protease K solution for 30 min. After incubation, 2 ml of 6 M NaCl was added and vigorously shaken several times, followed by centrifugation at 12,000 rpm for 5 min. The supernatant was transferred and 2 volumes of absolute ethanol was added.

Unexplored genomic control regions yield the key to finding causes of rare diseaseScientists have discovered the cause of a rare condition within a part of the genome that has been largely unexplored in medical genetics. A team at the University of Exeter has found genetic changes in a region that controls the activity of the genome, turning on or off genes, and in doing so they have found a key that could unlock other causes of rare conditions.

Mendelian randomization analysis of factors related to ovulation and reproductive function and endometrial cancer risk - BMC MedicineBackground Observational epidemiological studies suggest a link between several factors related to ovulation and reproductive function and endometrial cancer (EC) risk; however, it is not clear whether these relationships are causal, and whether the risk factors act independently of each other. The aim of this study was to investigate putative causal relationships between the number of live births, age at last live birth, and years ovulating and EC risk. Methods We conducted a series of observational analyses to investigate various risk factors and EC risk in the UK Biobank (UKBB). Additionally, multivariate analysis was performed to elucidate the relationship between the number of live births, age at last live birth, and years ovulating and other related factors such as age at natural menopause, age at menarche, and body mass index (BMI). Secondly, we used Mendelian randomization (MR) to assess if these observed relationships were causal. Genome-wide significant single nucleotide polymorphisms (SNPs) were extracted from previous studies of woman’s number of live births, age at menopause and menarche, and BMI. We conducted a genome-wide association analysis using the UKBB to identify SNPs associated with years ovulating, years using the contraceptive pill, and age at last live birth. Results We found evidence for a causal effect of the number of live births (inverse variance weighted (IVW) odds ratio (OR): 0.537, p = 0.006), the number of years ovulating (IVW OR: 1.051, p = 0.014), in addition to the known risk factors BMI, age at menarche, and age at menopause on EC risk in the univariate MR analyses. Due to the close relationships between these factors, we followed up with multivariable MR (MVMR) analysis. Results from the MVMR analysis showed that number of live births had a causal effect on EC risk (OR: 0.783, p=0.036) independent of BMI, age at menarche and age at menopause. Conclusions MVMR analysis showed that the number of live births causally reduced the ri
