Characterization of large structural genetic mosaicism in human autosomes

Abstract

Analyses of genome-wide association study (GWAS) data have revealed that detectable genetic mosaicism involving large (>2 Mb) structural autosomal alterations occurs in a fraction of individuals. We present results for a set of 24,849 genotyped individuals (total GWAS set II [TGSII]) in whom 341 large autosomal abnormalities were observed in 168 (0.68%) individuals. Merging data from the new TGSII set with data from two prior reports (the Gene-Environment Association Studies and the total GWAS set I) generated a large dataset of 127,179 individuals; we then conducted a meta-analysis to investigate the patterns of detectable autosomal mosaicism (n = 1,315 events in 925 [0.73%] individuals). Restricting to events >2 Mb in size, we observed an increase in event frequency as event size decreased. The combined results underscore that the rate of detectable mosaicism increases with age (p value = 5.5 × 10(-31)) and is higher in men (p value = 0.002) but lower in participants of African ancestry (p value = 0.003). In a subset of 47 individuals from whom serial samples were collected up to 6 years apart, complex changes were noted over time and showed an overall increase in the proportion of mosaic cells as age increased. Our large combined sample allowed for a unique ability to characterize detectable genetic mosaicism involving large structural events and strengthens the emerging evidence of non-random erosion of the genome in the aging population.

Proportion of Mosaic Individuals across 5-Year Age Groups in the Combined GENEVA, TGSI, and TGSII Dataset by Cancer Status Affected individuals are in red, and cancer-free control individuals are in blue. Error bars represent 95% CIs. An overall significant relationship in the proportion of individuals with mosaic events was observed with age (p value = 1.1×10−30).

Relationship between Mosaic Event Size and Detected Rate Counts of detected mosaic events from the combined analysis are plotted in 10-Mb bin sizes. An inverse exponential trend, represented by the dotted line, was fit to the counts (R2 = 0.81). Fitted coefficients (β) and 95% CIs are displayed in the plot.

Event Size and Mosaic-Proportion Distribution across Copy-Number State Violin plots of combined sample event size (A) and mosaic proportion (B) in relationship to mosaic copy gains, copy-neutral uniparental disomies, and copy losses. Boxplots with white circles denoting the median and thick black boxes representing the interquartile range are encapsulated in kernel density plots of the distribution of event length. Numbers below and above the violin plots of mosaic proportion (B) indicate the minimum and maximum detected range observed for each respective event’s copy-number state.

Characterization of Changes in Mosaic Proportion with Age Mosaic proportion is stratified across event copy-number state (columns) and age category (x axis) from the combined analysis. Points represent estimates of the mean, and error bars indicate 95% CI around the mean. Best-fit regression lines are plotted with dotted lines, and p values are shown for slopes that are significantly different from 0.

Changes in Percentage of Mosaicism of Serial Samples over Time (A) Lines (red for copy loss, blue for copy neutral, and green for copy gain) connect DNA-collection time points (triangles represent males, and circles represent females) for each mosaic chromosome (n = 58) to track changes in the percentage of mosaicism with increasing age. (B) Events are plotted with zero origin and a mixed model for a subject with zero random-effect fit (solid black line), showing the estimated average change in mosaic proportion per year (1.44%, p value = 3.3 × 10−7).
