Mouse lines carrying:
Mazem#Mhll mutation (0 available); any Maz mutation (21 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
lethality throughout fetal growth and development, incomplete penetrance ( J:257647 )
• fewer than expected mice are present at E16.5 and E18.5
postnatal lethality, incomplete penetrance ( J:257647 )
• further lethality is observed by P13

reproductive system

• in the surviving male mouse despite normal testis and epididymal morphology

renal/urinary system
renal hypoplasia ( J:257647 )
• in the surviving mouse
absent kidney ( J:257647 )
• in some mice
single kidney ( J:257647 )
• in the surviving male mouse despite normal ureter development

cardiovascular system
abnormal heart atrium morphology ( J:257647 )
• mismatched atrial size in the surviving male mouse despite normal heart size
• however, no obstructions are observed

growth/size/body
