Variant summary: The NPHS1 c.2335-1G>A variant involves the alteration of a conserved intronic nucleotide and 4/5 splice prediction tools predict a significant impact on normal splicing and ESE finder predicts alterations to ESE binding sites. However, these predictions have yet to be confirmed by functional studies. This variant was found in 7/121044 control chromosomes at a frequency of 0.0000578, which does not exceed the estimated maximal expected allele frequency of a pathogenic NPHS1 variant (0.0033541). Multiple publications have cited the variant in homozygous and compound heterozygous affected individuals. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely pathogenic. Taken together, this variant is classified as pathogenic. (less)

A heterozygous canonical splice-site variant, NM_004646.3(NPHS1):c.2335-1G>A, has been identified in intron 17 of 28 of the NPHS1 gene. The variant is likely to cause a splice defect, resulting in an altered protein length. The nucleotide at this position has very high conservation (Phylop UCSC). This nucleotide substitution is predicted to cause aberrant splicing of the gene and may result in a truncated protein; further testing via RNA studies are required to confirm if splicing is altered. The variant is present in the gnomAD database at a frequency of 0.009% (24 heterozygotes and 0 homozygotes). The variant has been reported multiple times as homozygous in patients with nephrotic syndrome (Bierzynska A. et al. (2017), Wong W. et al. (2013), Koziell A. et al. (2002), ClinVar). Based on the information available at the time of curation, this variant has been classified as PATHOGENIC. (less)

This variant is expected to severely impact normal RNA splicing, and consequently, protein structure and/or function. The frequency of this variant in the general population is consistent with pathogenicity (http://gnomad.broadinstitute.org). This variant has been identified in at least one individual with clinical features associated with this gene. In multiple individuals, this variant has been seen with a single recessive pathogenic variant in the same gene, suggesting this variant may also be pathogenic. (less)

NM_004646.3(NPHS1):c.2335-1G>A is a canonical splice variant classified as pathogenic in the context of nephrotic syndrome, NPHS1-related. c.2335-1G>A has been observed in cases with relevant disease (PMID: 11854170, 20507940, 23949594, 28117080). Functional assessments of this variant are not available in the literature. c.2335-1G>A has been observed in population frequency databases (gnomAD: NFE 0.02%). In summary, NM_004646.3(NPHS1):c.2335-1G>A is a canonical splice variant in a gene where loss of function is a known mechanism of disease, is predicted to disrupt protein function, and has been observed more frequently in cases with the relevant disease than in healthy populations. Please note: this variant was assessed in the context of healthy population screening. (less)

This sequence change affects an acceptor splice site in intron 17 of the NPHS1 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in NPHS1 are known to be pathogenic (PMID: 11317351, 11854170, 12039988). This variant is present in population databases (rs150038620, gnomAD 0.02%). Disruption of this splice site has been observed in individuals with congenital nephrotic syndrome (PMID: 9915943, 11854170, 24902943, 28117080). ClinVar contains an entry for this variant (Variation ID: 188734). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. (less)

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number.
