PROBLEM: Question: Is haploinsufficiency the key mechanism of pathogenesis in a heterozygous Elovl4 knockout mouse model of STGD3 disease?
Answer: The detailed characterization of this animal model provides the first in vivo evidence that Elovl4 haploinsufficiency is not the underlying key disease mechanism in STGD3. The results are consistent with a dominant negative mechanism for the deletion mutation. The Elovl4 knockout mouse is one of three complementary animal models that will help elucidate the disease mechanism.

SOLUTION: no
