Autosomal recessive polycystic kidney disease Uncertain:2
Uncertain significance, no assertion criteria provided | clinical testing | Natera, Inc. | Sep 12, 2018 | - - |
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Apr 25, 2022 | This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 2576 of the PKHD1 protein (p.Ile2576Val). This variant is present in population databases (rs565528098, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with PKHD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 406888). 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 not expected to disrupt PKHD1 protein function. 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. - |
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 23, 2023 | The c.7726A>G (p.I2576V) alteration is located in exon 48 (coding exon 47) of the PKHD1 gene. This alteration results from a A to G substitution at nucleotide position 7726, causing the isoleucine (I) at amino acid position 2576 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
