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=0.024544388).
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000408 (62/152106) while in subpopulation AFR AF= 0.00142 (59/41430). AF 95% confidence interval is 0.00113. There are 0 homozygotes in gnomad4. There are 30 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2021The c.131C>G (p.P44R) alteration is located in exon 3 (coding exon 2) of the SLC34A2 gene. This alteration results from a C to G substitution at nucleotide position 131, causing the proline (P) at amino acid position 44 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
