Pathogenic, criteria provided, single submitter | clinical testing | Wong Mito Lab, Molecular and Human Genetics, Baylor College of Medicine | Aug 10, 2017 | The NM_012160.4:c.1317G>A (NP_036292.2:p.Glu439=) [GRCH38: NC_000006.12:g.98899268C>T] variant in FBXL4 gene is interpretated to be a Pathogenic based on ACMG guidelines (PMID: 25741868). This variant meets one or more of the following evidence codes reported in the ACMG-guideline. PVS1:This variant is a predcted null variant in FBXL4 where loss of function is a known mechanism of disease. PM2:This variant is absent in key population databases. PP4:Patient’s phenotype or family history is highly specific for FBXL4. PP5:Reputable source(s) suggest that the variant is pathogenic. Based on this evidence code ClinGen Pathogenicity Calculator (PMID:28081714) suggested that the variant is Pathogenic. - |
