Genes affected
TRAPPC4 (HGNC:19943): (trafficking protein particle complex subunit 4) Involved in autophagy and endoplasmic reticulum to Golgi vesicle-mediated transport. Part of TRAPP complex. [provided by Alliance of Genome Resources, Apr 2022]
RPS25 (HGNC:10413): (ribosomal protein S25) 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 40S subunit. The protein belongs to the S25E 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]
