Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong

The NM_001177316.2(SLC34A3):c.203G>A(p.Arg68His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000199 in 1,610,970 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R68G) has been classified as Uncertain significance.

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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.203G>A (p.R68H) alteration is located in exon 4 (coding exon 3) of the SLC34A3 gene. This alteration results from a G to A substitution at nucleotide position 203, causing the arginine (R) at amino acid position 68 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
