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_pathogenic. Variant got 6 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.0660878 fraction of the gene. Cryptic splice site detected, with MaxEntScore 9.7, offset of 3, new splice context is: ccttttgcttgtttcggcAGata. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 4-25662703-A-G is Pathogenic according to our data. Variant chr4-25662703-A-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 981832.Status of the report is criteria_provided_single_submitter, 1 stars.
