Why it matters in GWAS

Association statistics are reported per variant with chromosomal position; sex chromosomes and pseudoautosomal regions need special QC and modeling compared with autosomes.

Example usage

"Karyotype review confirmed chromosome-level abnormalities in samples flagged during QC."

Click any node to open that term page.

Node order. The current term is first. Next come every page linked from Related terms, in the same top-to-bottom order as that list. Then new terms appear in two-hop layers: for each of those direct neighbors (in that same order), their related terms are appended if not already listed. A third pass does the same for two-hop nodes. The walk stops when a fixed maximum number of nodes is reached.
