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]

SLC9A3R1-AS1 (HGNC:55322): (SLC9A3R1 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BP6: Variant 17-74748772-G-A is Benign according to our data. Variant chr17-74748772-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 1315840.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr17-74748772-G-A is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.021 (3201/152254) while in subpopulation NFE AF= 0.0323 (2197/67990). AF 95% confidence interval is 0.0312. There are 49 homozygotes in gnomad4. There are 1480 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd at 3202 AD gene.
