Variant summary
Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PP3_Strong
The NM_003052.5(SLC34A1):c.536T>C(p.Leu179Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000378 in 1,613,428 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 14/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. L179L) has been classified as Likely benign.

This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 179 of the SLC34A1 protein (p.Leu179Pro). This variant is present in population databases (rs142772770, gnomAD 0.006%). This missense change has been observed in individual(s) with nephrocalcinosis (PMID: 28893421). ClinVar contains an entry for this variant (Variation ID: 548680). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
