Variant summary

Our verdict is Benign. Variant got -13 ACMG points: 1P and 14B. PP2BP4_StrongBP6_ModerateBS1BS2

The NM_001257180.2(SLC20A2):c.1934T>A(p.Met645Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000147 in 1,614,116 control chromosomes in the GnomAD database, including 3 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M645V) has been classified as Uncertain significance.

Genes affected

SLC20A2 (HGNC:10947): (solute carrier family 20 member 2) This gene encodes a member of the inorganic phosphate transporter family. The encoded protein is a type 3 sodium-dependent phosphate symporter that plays an important role in phosphate homeostasis by mediating cellular phosphate uptake. The encoded protein also confers susceptibility to viral infection as a gamma-retroviral receptor. Mutations in this gene may play a role in familial idiopathic basal ganglia calcification. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Mar 2012]
