Increased DNA Copy Number Variation Mosaicism in Elderly Human Brain

Table 2

Comparison of length and gene content of the in common and unique CNVs from the frontal cortex and cerebellum.

Copy number variation	CNVs in common to both tissues	Unique CNVs (frontal cortex)	Unique CNVs (cerebellum)
Mean size of CNVs (kb)	319 ± 85/	295 ± 60/	436 ± 84/
Deletions (Kb) ()^#	151 ± 32/	299 ± 88/	478 ± 103/
Duplications (kb) ()	760 ± 261/	290 ± 72/	301 ± 125/
Gene content (kb)	1.33 ± 0.23/	1.57 ± 0.19/	1.38 ± 0.27/
