Variant summary

Our verdict is Benign. Variant got -18 ACMG points: 2P and 20B. PM5BP4_StrongBP6_Very_StrongBS1BS2

The NM_014270.5(SLC7A9):c.1444C>T(p.Pro482Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000639 in 1,613,982 control chromosomes in the GnomAD database, including 6 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/20 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. P482L) has been classified as Likely pathogenic.

Genes affected

SLC7A9 (HGNC:11067): (solute carrier family 7 member 9) This gene encodes a protein that belongs to a family of light subunits of amino acid transporters. This protein plays a role in the high-affinity and sodium-independent transport of cystine and neutral and dibasic amino acids, and appears to function in the reabsorption of cystine in the kidney tubule. Mutations in this gene cause non-type I cystinuria, a disease that leads to cystine stones in the urinary system due to impaired transport of cystine and dibasic amino acids. Alternate transcript variants, which encode the same protein, have been found for this gene. [provided by RefSeq, Jul 2011]
