The ABC transporter subfamily A member ABCA5 is thought to mediate cholesterol (CHOL) efflux from lysosomes (Petry et al. 2003). ABCA5 defects are associated with autosomal recessive congenital generalised hypertrichosis terminalis (CGHT; MIM:135400). Lysosomal function is reduced with an accumulation of autophagosomes and their cargo as well as increased endolysosomal cholesterol in CGHT keratinocytes, resulting in hair overgrowth (DeStefano et al. 2014).
