Invitae | RCV001225919 | SCV001398213 | uncertain significance | Congenital myasthenic syndrome 8 | 2021-08-13 | criteria provided, single submitter | clinical testing | This sequence change replaces tyrosine with aspartic acid at codon 1877 of the AGRN protein (p.Tyr1877Asp). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and aspartic acid. This variant is present in population databases (rs755383095, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with AGRN-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. |

RCV001225919 | SCV004012807 | not provided | Congenital myasthenic syndrome 8 | no assertion provided | phenotyping only | Variant interpreted as Uncertain significance and reported on 06-14-2021 by Lab The Children's Hospital of Philadelphia. Assertions are reported exactly as they appear on the patient provided laboratory report. GenomeConnect does not attempt to reinterpret the variant. The IDDRC-CTSA National Brain Gene Registry (BGR) is a study funded by the U.S. National Center for Advancing Translational Sciences (NCATS) and includes 13 Intellectual and Developmental Disability Research Center (IDDRC) institutions. The study is led by Principal Investigator Dr. Philip Payne from Washington University. The BGR is a data commons of gene variants paired with subject clinical information. This database helps scientists learn more about genetic changes and their impact on the brain and behavior. Participation in the Brain Gene Registry requires participation in GenomeConnect.
