Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 6P and 2B. PM1PM2PM5BP4_Moderate

The NM_014625.4(NPHS2):ā€‹c.1121A>Cā€‹(p.Asn374Thr) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,461,848 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N374Y) has been classified as Likely pathogenic.

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]
AXDND1 (HGNC:26564): (axonemal dynein light chain domain containing 1)

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 16, 2024The c.1121A>C (p.N374T) alteration is located in exon 8 (coding exon 8) of the NPHS2 gene. This alteration results from a A to C substitution at nucleotide position 1121, causing the asparagine (N) at amino acid position 374 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
