Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1

The NM_015102.5(NPHP4):​c.3851G>A​(p.Arg1284His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00011 in 1,595,804 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 17/22 in silico tools predict 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. R1284C) has been classified as Likely benign.

Genes affected
NPHP4 (HGNC:19104): (nephrocystin 4) This gene encodes a protein involved in renal tubular development and function. This protein interacts with nephrocystin, and belongs to a multifunctional complex that is localized to actin- and microtubule-based structures. Mutations in this gene are associated with nephronophthisis type 4, a renal disease, and with Senior-Loken syndrome type 4, a combination of nephronophthisis and retinitis pigmentosa. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2014]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.008154035).
BP6
Variant 1-5864483-C-T is Benign according to our data. Variant chr1-5864483-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 286996.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000637 (97/152320) while in subpopulation AFR AF = 0.00224 (93/41586). AF 95% confidence interval is 0.00187. There are 1 homozygotes in GnomAd4. There are 42 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
