Variant summary
Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PVS1_StrongPM2PP5
The NM_003982.4(SLC7A7):c.1262del(p.Pro421ArgfsTer98) variant causes a frameshift change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely pathogenic (no stars). Synonymous variant affecting the same amino acid position (i.e. P421P) has been classified as Likely benign.

Genes affected
SLC7A7 (HGNC:11065): (solute carrier family 7 member 7) The protein encoded by this gene is the light subunit of a cationic amino acid transporter. This sodium-independent transporter is formed when the light subunit encoded by this gene dimerizes with the heavy subunit transporter protein SLC3A2. This transporter is found in epithelial cell membranes where it transfers cationic and large neutral amino acids from the cell to the extracellular space. Defects in this gene are a cause of lysinuric protein intolerance (LPI). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2011]

ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 7 ACMG points.
PVS1
?
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most 50 bp of the penultimate exon, not predicted to undergo nonsense mediated mRNA decay. There are 16 pathogenic variants in the truncated region.
PM2
?
Very rare variant in population databases, with high coverage;
PP5
?
Variant 14-22774099-CG-C is Pathogenic according to our data. Variant chr14-22774099-CG-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 56353.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr14-22774099-CG-C is described in Lovd as [Pathogenic].
