I have been analyzing TCGA Ovary Cancer data. In Somatic Mutation data, there is data of mutations in all the chromosomes (1-22 and X), but amazingly, I have found one (just one) row of Y Chromosome mutation as well. What can it mean?
For Reference, I have pasted that row below:
icgc_mutation_id icgc_donor_id project_code chromosome chromosome_start MU42454 DO28056 OV-US Y 13500742 chromosome_end chromosome_strand mutation_type 13500742 1 single base substitution reference_genome_allele mutated_from_allele mutated_to_allele G G A consequence_type aa_mutation cds_mutation gene_affected transcript_affected stop_gained R194* 580C>T ENSG00000183704 ENST00000331172
