N
• no embryonic lethality is observed in mice maternally inheriting the Ascl2tm1Alj allele

cellular
• embryonic lethality associated with maternal transmission of Ascl2tm1Alj allele is prevented by the addition of the Kcnq1tm1.1Mjh allele due to a lack of paternal imprinting of genes in the distal portion of chromosome 7
