Albinismo oca2
WebOca2 appears to regulate iridophore number and location via non-cell autonomous mechanism. Although oca2 does appear to be expressed in iridophores, the magnitude is very small. Oca2 does not appear to control differentiation. Changes in both pnp4a and mitfa expression between mutant and wildtype larvae occur later in development, indicating … WebThe .gov means it's official.
