Genetic Discrimination and Misuse of Genetic Information: Areas of Possible Discrimination, Current Legislation, and Potential Limitations
SG Lee et al, CDC Blog Post, October 3, 2022 Brand

The emergence and the rapid development of various genetic technologies and their incorporation into precision medicine have greatly expanded medicine’s capabilities. At the same time, concerns about the availability and dissemination of vast amounts of personally relevant data have focused attention on potential problems of genetic discrimination.

Parental Preferences about Policy Options Regarding Disclosure of Incidental Genetic Findings in Newborn Screening: Using Videos and the Internet to Educate and Obtain Input
MH Farrell et al, IJNS, September 2022

Data from value comparisons suggested that parents believed knowing everything was very important even if they became distressed. Likewise, parents preferred autonomy even if they became distressed. However, when there might not be enough time to learn everything, parents showed a slight preference for deferring decision-making. Because most parents strongly preferred the policies of full disclosure or making the decision, rather than the withholding option for NBS results, these results can inform disclosure policies in NBS programs.

Psychosocial Issues Related to Newborn Screening: A Systematic Review and Synthesis
A Tluzcek et al, IJNS, September 2022

Psychosocial consequences of receiving unexpected neonatal screening results and unsolicited genetic information remain significant risks to expansion of NBS. Findings suggest that risks may be mitigated by improved parent NBS education, effective communication, individualized genetic counseling, and anticipatory developmental guidance. Clinicians need to take extra measures to ensure equitable service delivery to marginalized subpopulations.

Personalized Prescription of Chemotherapy Based on Assessment of mRNA Expression of BRCA1, RRM1, ERCC1, TOP1, TOP2α, TUBβ3, TYMS, and GSTP1 Genes in Tumors Compared to Standard Chemotherapy in the Treatment of Non-Small-Cell Lung Cancer
MM Tsyganov et al, J Per Medicine, October 4, 2022

MFS and OS were significantly better in the personalized chemotherapy group compared to the classic chemotherapy group (MFS, 46.22 vs. 22.9 months, p = 0.05; OS, 58.6 vs. 26.9 months, p < 0.0001). Importantly, the best metastasis-free survival rates in the group with personalized ACT were achieved in patients treated with the paclitaxel/carboplatin regimen. Based on an assessment of chemosensitivity gene expression in the tumors, the classical chemotherapy strategy also increased the risk of death (HR = 14.82; 95% CI: 3.33–65.86; p < 0.000) but not metastasis (HR = 1.95; 95% CI: 0.96–3.98; p = 0.06) compared to the group of patients with chemotherapy.
