Variant summary

Our verdict is Benign. The variant received -19 ACMG points: 1P and 20B. PP2BP4_StrongBP6_Very_StrongBS1BS2

The NM_014625.4(NPHS2):​c.182C>T​(p.Ala61Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000937 in 1,596,352 control chromosomes in the GnomAD database, including 12 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A61T) has been classified as Uncertain significance.

Genes affected
NPHS2 (HGNC:13394): (NPHS2 stomatin family member, podocin) This gene encodes a protein that plays a role in the regulation of glomerular permeability. Mutations in this gene cause steroid-resistant nephrotic syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]
NPHS2 Gene-Disease associations (from GenCC):
  • nephrotic syndrome, type 2
    Inheritance: AR, AD Classification: DEFINITIVE, STRONG, LIMITED Submitted by: Myriad Women’s Health, Ambry Genetics, Labcorp Genetics (formerly Invitae), Illumina, G2P
  • familial idiopathic steroid-resistant nephrotic syndrome

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -19 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 29 curated pathogenic missense variants (we use a threshold of 10). The gene has 4 curated benign missense variants. Gene score misZ: 0.68612 (below the threshold of 3.09). Trascript score misZ: 0.038296 (below the threshold of 3.09). GenCC associations: The gene is linked to nephrotic syndrome, type 2, familial idiopathic steroid-resistant nephrotic syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.005782157).
BP6
Variant 1-179575683-G-A is Benign according to our data. Variant chr1-179575683-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 447877.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00524 (798/152310) while in subpopulation AFR AF = 0.0184 (767/41584). AF 95% confidence interval is 0.0174. There are 6 homozygotes in GnomAd4. There are 371 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 6 AR,AD gene
