Genes affected

SLC34A3 (HGNC:20305): (solute carrier family 34 member 3) This gene encodes a member of SLC34A transporter family of proteins, and is expressed primarily in the kidney. It is involved in transporting phosphate into cells via sodium cotransport in the renal brush border membrane, and contributes to the maintenance of inorganic phosphate concentration in the kidney. Mutations in this gene are associated with hereditary hypophosphatemic rickets with hypercalciuria. Alternatively spliced transcript variants varying in the 5' UTR have been found for this gene.[provided by RefSeq, Apr 2010]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 9-137231952-C-T is Benign according to our data. Variant chr9-137231952-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 1213253.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr9-137231952-C-T is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0102 (1547/152344) while in subpopulation NFE AF= 0.0166 (1132/68026). AF 95% confidence interval is 0.0158. There are 10 homozygotes in gnomad4. There are 738 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 10 AR gene
