Genes affected

PPP2R3C (HGNC:17485): (protein phosphatase 2 regulatory subunit B''gamma) This gene encodes a regulatory subunit of the serine/threonine phosphatase, protein phosphatase 2. This protein is localized to both nuclear and cytoplasmic regions depending on cell cycle phase. Homozygous conditional knockout mice for this gene exhibit reduced numbers and impaired proliferation of immune system B cells. This protein may regulate the expression of the P-glycoprotein ATP-binding cassette transporter through its phosphatase activity. Alternative splicing results in multiple transcript variants.

FAM177A1 (HGNC:19829): (family with sequence similarity 177 member A1) This gene encodes a member of a conserved protein family. Alternative splicing results in multiple transcript variants. This gene is thought to be associated with susceptibility to juvenile idiopathic arthritis. [provided by RefSeq, Apr 2017]

The c.1238A>G (p.N413S) alteration is located in exon 13 (coding exon 13) of the PPP2R3C gene. This alteration results from a A to G substitution at nucleotide position 1238, causing the asparagine (N) at amino acid position 413 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
