• 8-week-old male mutants do not show differences in body weight, daily food intake, ad libitum-fed blood glucose levels, or overnight fasted blood glucose levels

• membrane resistance of Pmch neurons is significantly reduced relative to wild-type neurons at 5 mM glucose
• almost all neurons do not hyperpolarize when extracellular glucose is reduced from 5 to 1 mM whereas around 70% of control neurons hyperpolarize under these conditions, indicating disrupted glucose-sensing

mortality/aging
• mice die within the first few days after birth

endocrine/exocrine glands
N
• mice do not exhibit endocrine-to-acinar fate conversion
• beta cells exhibit normal cell proliferation and apoptosis
• beta cell differentiation is impaired with insulin+ cells that are polyhormonal and ectopically express alpha cell markers unlike in control cells
• due to reduced differentiation without an effect on proliferation and apoptosis

mortality/aging
• mice die following E10.5 and are completely absorbed by E11.5
• however, treatment with a calcium channel agonist, 1 umol/L (-)-BayK 8644, partially rescues embryonic lethality with mice surviving until the end of E11.5

cardiovascular system
• at E10.5, a stenosis is frequently observed between the emerging right ventricle and the outflow tract
• at E10.5, mice display abnormal heart looping
• at E10.5, mice display abnormal heart looping with amorphous heart tubes lying distorted within the pericardial cavity, and a stenosis is frequently observed between the emerging right ventricle and the outflow tract
• at E10.5, pericardial effusion is associated with hemorrhages
• at E10.5, hearts only exhibit barely noticeable tremors without any noticeable ejection volume
• at E10.5, pericardial effusion is associated with hemorrhages
• 63+/-2.88 beats per minute compared to 120+/-3.15 beats per minute in wild-type mice
• however, no difference in heart rate is observed at E9.5
• at E10.5, L-type calcium channel activity and calcium-induced calcium release is impaired resulting in diminished heart pumping
• calcium channel current density is reduced compared to in wild-type mice
• unlike wild-type cardiomyocytes, E9.5 cardiomyocytes fail to respond to catecholamine treatment

embryo
• unlike in wild-type mice, embryos size does not double between E9.5 and E10.5
• at E9.5, vascular remodeling of the primary capillary plexus fails to occur and a honeycomb-like network of tubules with enlarged and uniform diameters forms in the extra- and intraembryonic vasculature

nervous system
• between E9.5 and E10.5

growth/size/body
• between E9.5 and E10.5, mice exhibit poor growth of facial primordial tissue
• unlike in wild-type mice, embryos size does not double between E9.5 and E10.5

craniofacial
• between E9.5 and E10.5, mice exhibit poor growth of facial primordial tissue

homeostasis/metabolism
• at E10.5, pericardial effusion is associated with hemorrhages

hematopoietic system
• very few hemangioblasts are found in the blood vessels of the yolk sac
