cellular

abnormal cilium morphology ( J:204004 )

vision/eye

abnormal retina photoreceptor morphology ( J:169232 )

• ciliary axoneme is reduced or absent, however the connecting cilium is intact and positioned appropriately

• stacks of outer segments are formed but do not organize into the extended vertical arrays

short photoreceptor outer segment ( J:169232 )

• early photoreceptor development occurs normally and all layers of the retina are present at P10 and P12, however, by P14, outer segment elongation is stalled and begins to regress
