The NM_001144967.3(NEDD4L):c.2752+6C>T variant causes a splice region, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0131 in 1,573,436 control chromosomes in the GnomAD database, including 207 homozygotes. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Likely benign (★★).
NEDD4L (HGNC:7728): (NEDD4 like E3 ubiquitin protein ligase) This gene encodes a member of the Nedd4 family of HECT domain E3 ubiquitin ligases. HECT domain E3 ubiquitin ligases transfer ubiquitin from E2 ubiquitin-conjugating enzymes to protein substrates, thus targeting specific proteins for lysosomal degradation. The encoded protein mediates the ubiquitination of multiple target substrates and plays a critical role in epithelial sodium transport by regulating the cell surface expression of the epithelial sodium channel, ENaC. Single nucleotide polymorphisms in this gene may be associated with essential hypertension. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Clinvar id is 241027.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr18-58390748-C-T is described in Lovd as [Likely_benign].
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.011 (1668/152240) while in subpopulation SAS AF= 0.032 (154/4816). AF 95% confidence interval is 0.0279. There are 17 homozygotes in gnomad4. There are 876 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
This variant is classified as benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
