Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2
The NM_012424.6(RPS6KC1):c.76G>A(p.Gly26Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,461,176 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G26R) has been classified as Uncertain significance.
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]
