Genes affected
SLC34A2 (HGNC:11020): (solute carrier family 34 member 2) The protein encoded by this gene is a pH-sensitive sodium-dependent phosphate transporter. Phosphate uptake is increased at lower pH. Defects in this gene are a cause of pulmonary alveolar microlithiasis. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, May 2010]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.048760563).
BS1
Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.0000315 (46/1461494) while in subpopulation AFR AF= 0.00117 (39/33474). AF 95% confidence interval is 0.000876. There are 0 homozygotes in gnomad4_exome. There are 19 alleles in male gnomad4_exome subpopulation. Median coverage is 34. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2023The c.296G>C (p.G99A) alteration is located in exon 4 (coding exon 3) of the SLC34A2 gene. This alteration results from a G to C substitution at nucleotide position 296, causing the glycine (G) at amino acid position 99 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
