The mean counts of autosomal variants and the median Phred scores per chromosome are shown for GRCh37 and GRCh38.

Columns: All: all detected variants; Common: listed in dbSNP common_all_*; Rare: variants that are not common.

The mean variant counts for chromosome X were 127,914 (GRCh37) and 132,177 (GRCh38). For chromosome Y, the mean counts could not be estimated since gender information was not available for all of the 121 in-house genomes. Both genome releases include the identical mitochondrial reference (NC_012920.1) with 27 variants
