ZFIN Phenotype Statement: photoreceptor outer segment layer retinal cone cell gnat2 expression decreased amount, abnormal

Phenotype:	photoreceptor outer segment layer retinal cone cell gnat2 expression decreased amount, abnormal
Note:	This phenotype statement describes a gene expression or antibody labeling pattern. Anatomy terms are combined with a gene or antibody and phenotype quality.

EXPRESSION ANATOMY:

Name:	photoreceptor outer segment layer
Synonyms:	photoreceptor outer segment layers
Definition:	Layer of the retina composed of the outer segments of the photoreceptor cells. The photoreceptor outer segment is a specialized primary cilium consisting of a microtubule-based axoneme and regular stacks of membrane folds or disks containing the photopigments (opsins) required for the phototransduction cascade.

Name:	retinal cone cell
Synonyms:	retinal cone cells
Definition:	One of the two photoreceptor cell types in the vertebrate retina. In cones the photopigment is in invaginations of the cell membrane of the outer segment. Cones are less sensitive to light than rods, but they provide vision with higher spatial and temporal acuity, and the combination of signals from cones with different pigments allows color vision.
