Genetic variants for head size share genes and pathways with cancer

Cell Reports Medicine, Journal Year: 2024, Volume and Issue: 5(5), P. 101529 - 101529

Published: May 1, 2024

The size of the human head is highly heritable, but genetic drivers its variation within general population remain unmapped. We perform a genome-wide association study on (N = 80,890) and identify 67 loci, which 50 are novel. Neuroimaging studies show that 17 variants affect specific brain areas, most have widespread effects. Gene set enrichment observed for various cancers p53, Wnt, ErbB signaling pathways. Genes harboring lead enriched macrocephaly syndrome genes (37-fold) high-fidelity cancer (9-fold), not seen height variants. Head also near preferentially expressed in intermediate progenitor cells, neural cells linked to evolutionary expansion. Our results indicate regulating early cranial growth incline neoplasia later life, irrespective height. This warrants investigation clinical implications link between cancer.

HSPA8 is involved in many stroke-associated cellular processes, playing a pivotal role the protein quality control system. Here we report results of pilot study aimed at determining whether SNPs are linked to risk ischemic stroke (IS). DNA samples from 2139 Russians (888 IS patients and 1251 healthy controls) were genotyped for tagSNPs (rs1461496, rs10892958, rs1136141) gene using probe-based PCR.

Background: Ischemic stroke (IS) is the leading cause of death and disability worldwide. Chaperone proteins protect brain cells from ischemic damage by restoring structures damaged proteins. C9orf16 (also known as BBLN) belongs to class heat-resistant obscure (HERO) proteins, characterized ability stabilize various suppress neurotoxicity reduce proteotoxic stress. In this regard, it may play a potentially significant role in risk development clinical manifestations IS. The aim study: To investigate an association between single nucleotide polymorphism rs2900262 gene encoding predisposition Materials methods: A total 897 patients with IS 1140 healthy controls were recruited for study. Genotyping was done using probe-based genotyping assay. Multiple logistic regression analysis performed evaluate associations genotypes events. Dominant, recessive additive models analyzed. Adjustment sex, age, smoking throughout. Benjamini-Hogberg false-discovery rate used correct multiple comparisons. Results: rs2900262*T allele found be associated increased exclusively females (dominant model: OR=1.74, 95% CI=1.07-2.82, PFDR=0.042; OR=1.69, CI=1.06-2.71, PFDR=0.042).
