Mx1 [Search on AGR]
Mus musculus PHENOTYPE: A2G, SL/NiA, T9 and CAST/Ei strains produce the MX1 protein (Mx1+ allele) conferring resistance to myxoviruses, whereas no protein is made by the Mx1- susceptible alleles of C57BL/6J and many other inbred strains with an exon 9-11 deletion; or CBA/J, CE/J, I/LnJ and PERA/Ei with a nonsense mutation.

Asmt [Search on AGR]
Mus musculus PHENOTYPE: Pineal melatonin synthesis requires enzymes encoded by Asmt and Aanat. C57BL/6, BALB/c, AKR/J, NZB/Bl, IS/Cam, and CAST/Ei carry the a allele of Asmt and lack melatonin. SK/Cam, SF/Cam, PERU, and FDS carry the b allele and have normal melatonin levels. [provided by MGI curators]
