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 GeneticsJan 31, 2024The c.61G>A (p.A21T) alteration is located in exon 2 (coding exon 1) of the SLC34A2 gene. This alteration results from a G to A substitution at nucleotide position 61, causing the alanine (A) at amino acid position 21 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
