ht1

• Allelic Composition: Atp7a^Mo-dp/Atp7a⁺
• Genetic Background: involves: 101/H * C3H/HeH

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

integument

variegated coat color ( J:220263 )

♀

curly vibrissae ( J:220263 )

♀ • variable penetrance

nervous system

decreased brain copper level ( J:220263 )

♀ • mean brain copper levels are about 25% lower than in wild-type females, although this is not significant due to small number of mice studied

pigmentation

variegated coat color ( J:220263 )

♀

homeostasis/metabolism

decreased noradrenaline level ( J:220263 )

♀ • in the brain

decreased brain copper level ( J:220263 )

♀ • mean brain copper levels are about 25% lower than in wild-type females, although this is not significant due to small number of mice studied

abnormal enzyme/coenzyme activity ( J:220263 )

♀ • the dihydroxyphenylacetic acid: dihydroxyphenylglycol (DOPAC:DHPG) ratio is about 3.5-fold increased and the dopamine:norepinephrine ratio is about 2.5-fold increased, indicating dopamine beta-hydroxylase (a copper-dependent enzyme) deficiency

integument

variegated coat color ( J:12943 )

♀

curly vibrissae ( J:12943 )

♀ • variable curling of the vibrissae

limbs/digits/tail

clubfoot ( J:12943 )

♀ • some females show clubbing of one or both fore feet at birth or at weaning

pigmentation

variegated coat color ( J:12943 )

♀

skeleton

abnormal skeleton morphology ( J:12943 )

♀ • some females develop calcified lumps in the region of the periosteum, especially on the vertebral column, particularly the thoracic and lumber regions with age
