Overview

A collaborative work was carried out by the Spanish and Portuguese ISFG Working Group (GEP‐ISFG) to estimate Y‐STR mutation rates. Seventeen Y chromosome STR loci (DYS19, DYS385, DYS389I and II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, DYS635 [GATA C4], GATA H4, and GATA A10) were analyzed in a sample of 3,026 father/son pairs. Among 27,029 allele transfers, 54 mutations were observed, with an overall mutation rate across the 17 loci of 1.998 × 10–3 (95% CI, 1.501 × 10–3 to 2.606 × 10–3). With just one exception, all of the mutations were single‐step, and they were observed only once per gametogenesis. Repeat gains were more frequent than losses, longer alleles were found to be more mutable, and the mutation rate seemed to increase with the father's age.
