Primary immunodeficiencyGene: RGS10
Comment on list classification: New gene added by Boaz Palterer. Single family with 3 affected sibs reported (PMID:34315806), who presented with short stature and immunodeficiency and harboured compound het variants in RGS10 that segregated with disease. However, the sibs also carried a heterozygous PIK3CD (E525K) variant that has previously been deemed pathogenic in Activated PI3 Kinase Delta Syndrome (APDS), a primary immunodeficiency. The variant was excluded as the father also carried the PIK3CD variant but was mostly healthy and none of the 3 affected sibs displayed the full spectrum of symptoms associated with APDS. Nonetheless, APDS is a clinically heterogeneous condition with variable penetrance among affected individuals and so the contribution of PIK3CD to the patients immune dysregulation cannot be completely ruled out.
There are no further reports of an association between RGS10 variants and immunodeficiency to date, and therefore rating Red until further evidence emerges.

Chinn et al. a kindred with three affected siblings presenting with short stature and immunodeficiency and segregating with biallelic variants in RGS10 (c.489_491del:p.E163del and c.G511T:p.A171S). The affected individuals exhibited systemic abnormalities directly related to the RGS10 mutations, including recurrent infections, hypergammaglobulinemia, profoundly reduced lymphocyte chemotaxis, abnormal lymph node architecture, and short stature due to growth hormone deficiency. Some functional data is presented.
