α7/utr^−/− mice exhibit normal weight gain and viability. A: The average weights of 10-day-old male wild-type, α7^−/−, utr^−/−, and α7/utr^−/− mice were not significantly different. B: The average weights of 21-day-old male wild-type, α7^−/−, utr^−/−, and α7/utr^−/− mice were not statistically different. C: Five-week-old α7/utr^−/− mice were phenotypically indistinguishable from wild-type animals.
