Cone-rod dystrophy-24 (CORD24) is characterized by night blindness, defective color vision, and reduced visual acuity. Macular atrophy, macular pigmentation deposits, and drusen-like deposits in the macula have been observed. Age at onset varies widely, from the first to the sixth decades of live (Kobayashi et al., 2000; Huang et al., 2013; Zenteno et al., 2023). For a general phenotypic description and discussion of genetic heterogeneity of CORD, see CORD2 (120970). [from OMIM]

Idiopathic CD4 lymphopenia (ICL) is a rare and heterogeneous syndrome defined by a reproducible reduction in the CD4 T-lymphocyte count (less than 300 cells per microliter or less than 20% of total T cells) in the absence of HIV infection or other known causes of immunodeficiency. ICL predisposes to infections and malignancy (summary by Gorska and Alam, 2012). [from OMIM]
