Invitae | RCV003084985 | SCV003483966 | uncertain significance | Autosomal recessive polycystic kidney disease | 2022-07-05 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine, which is neutral and polar, with histidine, which is basic and polar, at codon 4040 of the PKHD1 protein (p.Gln4040His). This variant is present in population databases (rs144399387, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with PKHD1-related conditions. 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. |
Ambry Genetics | RCV003358092 | SCV004065104 | uncertain significance | Inborn genetic diseases | 2023-06-28 | criteria provided, single submitter | clinical testing | The c.12120A>C (p.Q4040H) alteration is located in exon 67 (coding exon 66) of the PKHD1 gene. This alteration results from a A to C substitution at nucleotide position 12120, causing the glutamine (Q) at amino acid position 4040 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
