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]

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PVS1

Splicing variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.

PP3

Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.

BP6

Variant 16-89903-C-G is Benign according to our data. Variant chr16-89903-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 542800.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000187 (26/1392886) while in subpopulation AMR AF= 0.000721 (25/34686). AF 95% confidence interval is 0.0005. There are 0 homozygotes in gnomad4_exome. There are 16 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.

BS2

High AC in GnomAdExome at 25 AD gene.
