Variant summary

Our verdict is Benign. Variant got -11 ACMG points: 0P and 11B. BP4_Strong BP6_Moderate BP7 BS2

The NM_001077350.3(NPRL3):​c.1113G>C​(p.Pro371=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000049 in 1,613,668 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Synonymous variant affecting the same amino acid position (i.e. P371P) has been classified as Likely benign.

Genes affected

NPRL3 (HGNC:14124): (NPR3 like, GATOR1 complex subunit) Contributes to GTPase activator activity. Involved in cellular response to amino acid starvation and negative regulation of TOR signaling. Located in lysosomal membrane. Part of GATOR1 complex. Implicated in focal epilepsy. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -11 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.68).
• BP6: Variant 16-92644-C-G is Benign according to our data. Variant chr16-92644-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 1593177.Status of the report is criteria_provided_single_submitter, 1 stars.
