Genes affected

RPS6KC1 (HGNC:10439): (ribosomal protein S6 kinase C1) Sphingosine kinase catalyzes the formation of sphingosine 1 phosphate, a lipid cellular messenger. The protein encoded by this gene can bind to sphingosine kinase and to phosphatidylinositol 3-phosphate, suggesting a role in sphingosine 1 phophate signaling. The encoded protein can also bind to peroxiredoxin-3 and may help transport it to mitochondria. [provided by RefSeq, Mar 2017]

Collection Method: clinical testing

The c.58C>A (p.P20T) alteration is located in exon 1 (coding exon 1) of the RPS6KC1 gene. This alteration results from a C to A substitution at nucleotide position 58, causing the proline (P) at amino acid position 20 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
