LAF4 Background Information LAF4 (lymphoid nuclear protein related to AF4), also known as AFF3 (AF4/FMR2 family, member 3), is a 1,226 amino acid nuclear protein that is preferentially expressed in lymphoid tissues and is thought to function as a transcriptional activator. Through its ability to interact with and bind to double-stranded DNA, LAF4 may be involved in lymphoid development and oncogenesis. The gene encoding LAF4 maps to human chromosome 2, which houses over 1,400 genes and comprises nearly 8% of the human genome. Harlequin icthyosis, a rare and morbid skin deformity, is associated with mutations in the ABCA12 gene, while the lipid metabolic disorder sitosterolemia is associated with defects in the ABCG5 and ABCG8 genes. Additionally, an extremely rare recessive genetic disorder, Alström syndrome, is caused by mutations in the ALMS1 gene, which maps to chromosome 2.
