Variant summary
Our verdict is Benign. Variant got -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2
The NM_001006658.3(CR2):c.524C>T(p.Pro175Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00618 in 1,614,062 control chromosomes in the GnomAD database, including 48 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/21 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. P175S) has been classified as Uncertain significance.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Mar 28, 2016 | Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: 0.7% in East asian in ExAC with 2 homozygotes and 0.58% in european with 1 homozygote. Reported in 1/36 patients with hemolytic syndrome who also carried a c.1160-2A>G variant in CFH (Bu 2014). However, even the association gene-disease is not that strong (moderate). - |

Uncertain significance, criteria provided, single submitter | clinical testing | Center for Genomics, Ann and Robert H. Lurie Children's Hospital of Chicago | Mar 30, 2021 | CR2 NM_001006658.2 exon 3 p.Pro175Leu (c.524C>T): This variant has been reported in the literature in 1 individual with atypical hemolytic uremic syndrome (aHUS) (Bu 2014 PMID:24029428). This variant is present in 0.6% (410/68028) of European alleles including 1 homozygote in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/1-207468605-C-T?dataset=gnomad_r3). This variant is present in ClinVar, with classifications ranging from Variant of Uncertain Significance to Likely Benign (Variation ID:402563). Evolutionary conservation and computational predictive tools suggest that this variant may not impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. - |
