Smith-Magenis syndrome chromosome region, candidate 5 (non-protein coding) (SMCR5)

Smith-Magenis syndrome chromosome region, candidate 5 (SMCR5), is a long non-coding RNA gene on chromosome 17 that does not encode a protein[3][5][9]. It is one of several genes found in the region commonly deleted in Smith-Magenis syndrome, a genetic disorder characterized by developmental delay and behavioral problems arising from deletions affecting multiple genes including RAI1, a gene with more direct pathogenic significance[11]. SMCR5 itself is not established as a therapeutic target, and while its specific biological functions are not well-characterized, lncRNAs are generally implicated in gene expression regulation, chromatin structure maintenance, and cell differentiation[2][6][8]. The existence of a SMCR5 protein product described in some sources is likely erroneous or at best unconfirmed, as major genomic databases list it solely as a non-protein coding RNA[3][5][7].
