TRAF6 (−/−) animals were derived from timed matings of TRAF6 (+/−) mice, with the morning of the plug designated as E0.5. No exencephaly was observed in TRAF6 (+/−) or (+/+) littermates. P14 represents the number of viable progeny observed at P14 derived from TRAF6 (+/−) mice in the mixed C57BL6 × 129J background or backcrossed more than two times onto either C57BL6 or outbred ICR/CD1 genetic backgrounds.
↵F1-a Indicates the number of animals exhibiting one or more wild-type allele(s) from intercrosses of C57BL6 TRAF6 (+/−) mice.
