Summaries for RPL21 Gene

Entrez Gene Summary for RPL21 Gene

  • Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 60S subunit. The protein belongs to the L21E family of ribosomal proteins. It is located in the cytoplasm. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Jul 2008]

  • Hypotrichosis 12 (HYPT12) [MIM:615885]: A form of hypotrichosis, a condition characterized by the presence of less than the normal amount of hair and abnormal hair follicles and shafts, which are thin and atrophic. The extent of scalp and body hair involvement can be very variable, within as well as between families. HYPT12 patients have normal scalp hair density at birth. Hair loss begins during the first 6 months of life and gradually progresses to nearly complete loss of scalp hair. The remaining hairs grow slowly and are thin, sparse, dry, and fragile. Body hair, axillary and pubic hair, eyebrows and eyelashes are also sparse or absent. {ECO:0000269 PubMed:21412954}. Note=The disease is caused by mutations affecting the gene represented in this entry.
