Variant summary

Our verdict is Benign. The variant received -12 ACMG points: 1P and 13B. PP2BP4_StrongBP6BS1BS2

The NM_198586.3(NHLRC1):​c.1091C>T​(p.Ser364Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000886 in 1,614,150 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S364T) has been classified as Uncertain significance.

Genes affected
NHLRC1 (HGNC:21576): (NHL repeat containing E3 ubiquitin protein ligase 1) The protein encoded by this gene is a single subunit E3 ubiquitin ligase. Laforin is polyubiquitinated by the encoded protein. Defects in this intronless gene lead to an accumulation of laforin and onset of Lafora disease, also known as progressive myoclonic epilepsy type 2 (EPM2).[provided by RefSeq, Mar 2010]
NHLRC1 Gene-Disease associations (from GenCC):
  • Lafora disease

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 13 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. Gene score misZ: 0.49521 (below the threshold of 3.09). Trascript score misZ: -0.085446 (below the threshold of 3.09). GenCC associations: The gene is linked to Lafora disease.
BP4
Computational evidence support a benign effect (MetaRNN=0.010530412).
BP6
Variant 6-18121516-G-A is Benign according to our data. Variant chr6-18121516-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 206182.
BS1
Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000105 (16/152290) while in subpopulation EAS AF = 0.00193 (10/5174). AF 95% confidence interval is 0.00105. There are 0 homozygotes in GnomAd4. There are 5 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 2 AR gene
