Homo sapiens

Also known as SRS; SpS; MRSR; SPMSY; MRXSSR

Gene ID: 6611 | Gene type: protein coding

About SMS

Cytogenetic location: Xp22.11 Genomic coordinates (GRCh38): X:21,940,709-21,994,837 (from NCBI)

This gene has 4 transcripts (splice variants), 241 orthologues, 1 paralogue and is associated with 3 phenotypes. Ubiquitous expression in prostate (RPKM 40.6), placenta (RPKM 32.9) and 24 other tissues.

Summary

This gene encodes a protein belonging to the spermidine/spermin synthase family and catalyzes the production of spermine from spermidine. Pseudogenes of this gene are located on chromosomes 1, 5, 6 and X. Mutations in this gene cause an X-linked intellectual disability called Snyder-Robinson Syndrome (SRS). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2017]
