UniProtKB AC	P78363 (Hs), O35600 (Mm)
Comment	Retinal-specific transporter of N-retinylPE; loss-of-function mutations are associated with childhood-onset Stargardt disease, a juvenile onset macular degenerative disease. The earlier onset disease is often associated with the more severe and deleterious ABCA4 variants [4]. ABCA4 facilitates the clearance of all-trans-retinal from photoreceptor disc membranes following photoexcitation. ABCA4 can also transport N-11-cis-retinylidene-phosphatidylethanolamine, the Schiff-base adduct of 11-cis-retinal; loss of function mutation cause a buildup of lipofuscin, atrophy of the central retina, and severe progressive loss in vision [6].

UniProtKB AC	Q8WWZ7 (Hs), Q8K448 (Mm), Q8CF82 (Rn)
Comment	ABCA5 is a lysosomal protein whose loss of function compromises integrity of lysosomes and leads to intra-endolysosomal accumulation of cholesterol. It has recently been associated with Congenital Generalized Hypertrichosis Terminalis (CGHT), a hair overgrowth syndrome, in a patient with a mutation in ABCA5 that significantly decreased its expression [1].

Comment	Reported to play a role in skin ceramide formation [10]. A recent study shows that ABCA12 expression also impacts cholesterol efflux from macrophages. ABCA12 is postulated to associate with ABCA1 and LXR beta, and stabilize expression of ABCA1. ABCA12 deficiency causes decreased expression of Abca1, Abcg1 and Nr1h2 [3].
