Genes affected
SPNS2 (HGNC:26992): (SPNS lysolipid transporter 2, sphingosine-1-phosphate) The protein encoded by this gene is a transporter of sphingosine 1-phosphate, a secreted lipid that is important in cardiovascular, immunological, and neural development. Defects in this gene are a cause of early onset progressive hearing loss. [provided by RefSeq, Jul 2016]
