Genes affected

NHERF1 (HGNC:11075): (NHERF family PDZ scaffold protein 1) This gene encodes a sodium/hydrogen exchanger regulatory cofactor. The protein interacts with and regulates various proteins including the cystic fibrosis transmembrane conductance regulator and G-protein coupled receptors such as the beta2-adrenergic receptor and the parathyroid hormone 1 receptor. The protein also interacts with proteins that function as linkers between integral membrane and cytoskeletal proteins. The protein localizes to actin-rich structures including membrane ruffles, microvilli, and filopodia. Mutations in this gene result in hypophosphatemic nephrolithiasis/osteoporosis type 2, and loss of heterozygosity of this gene is implicated in breast cancer.[provided by RefSeq, Sep 2009]

The SLC9A3R1 p.Gly30Glu variant was not identified in the literature nor was it identified in ClinVar, Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs751217204) and it was identified in control databases in 4 of 259670 chromosomes at a frequency of 0.000015 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: European (non-Finnish) in 4 of 117636 chromosomes (freq: 0.000034), while the variant was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish), Other and South Asian populations. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. The p.Gly30 residue is conserved in mammals but not in more distantly related organisms, and four out of five computational analyses (PolyPhen-2, SIFT, BLOSUM, MutationTaster) suggest that the G variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
