Genes affected
SDCCAG8 (HGNC:10671): (SHH signaling and ciliogenesis regulator SDCCAG8) This gene encodes a centrosome associated protein. This protein may be involved in organizing the centrosome during interphase and mitosis. Mutations in this gene are associated with retinal-renal ciliopathy. [provided by RefSeq, Oct 2010]

SDCCAG8-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesJul 02, 2024The SDCCAG8 c.11C>T variant is predicted to result in the amino acid substitution p.Ser4Phe. This variant has been reported in a patient with renal agenesis, although conclusive evidence of pathogenicity was not presented (Table S4, Nicolaou et al. 2016. PubMed ID: 26489027). This variant is reported in 0.0033% of alleles in individuals of South Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
