Variant summary
Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3PP5
The NM_001177316.2(SLC34A3):c.846G>A(p.Pro282Pro) variant causes a splice region, synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000416 in 1,612,238 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. P282P) has been classified as Uncertain significance.

Synonymous variant c.846G>A in SLC34A3 could be classified as likely pathogenic variant according to ACMG criteria (PM2, PS3, PM3). The variant vas observed in 12 y.o. female patient with hypophosphatemic rickets with hypercalciuria in compound heterozygous state with c.1304delG variant in SLC34A3 gene. -

This sequence change affects codon 282 of the SLC34A3 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the SLC34A3 protein. This variant also falls at the last nucleotide of exon 8, which is part of the consensus splice site for this exon. This variant is present in population databases (rs121918236, gnomAD 0.005%). This variant has been observed in individual(s) with hypophosphatemic rickets with hypercalciuria (PMID: 16358215, 31672324, 33223529, 34805638). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 1429). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
