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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 04, 2023The c.233C>T (p.S78L) alteration is located in exon 3 (coding exon 2) of the SLC34A2 gene. This alteration results from a C to T substitution at nucleotide position 233, causing the serine (S) at amino acid position 78 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
