Variant summary
Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PP3_Strong
The NM_015102.5(NPHP4):c.3403C>T(p.Arg1135Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000242 in 1,613,172 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1135H) has been classified as Uncertain significance.

Inborn genetic diseases Uncertain:1
The c.3403C>T (p.R1135C) alteration is located in exon 24 (coding exon 23) of the NPHP4 gene. This alteration results from a C to T substitution at nucleotide position 3403, causing the arginine (R) at amino acid position 1135 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Nephronophthisis Uncertain:1
In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NPHP4 protein function. ClinVar contains an entry for this variant (Variation ID: 499341). This variant has not been reported in the literature in individuals affected with NPHP4-related conditions. This variant is present in population databases (rs374387338, gnomAD 0.03%), including at least one homozygous and/or hemizygous individual. This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 1135 of the NPHP4 protein (p.Arg1135Cys). -
