GeneDx	RCV000192864	SCV000168555	likely benign	not specified	2018-02-27	criteria provided, single submitter	clinical testing	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	RCV001093246	SCV002048979	uncertain significance	not provided	2023-10-20	criteria provided, single submitter	clinical testing	The FKRP c.1177G>A; p.Val393Ile variant (rs140679502), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 137380). This variant is found in the African population with an allele frequency of 0.7% (162/24462 alleles, including 1 homozygote) in the Genome Aggregation Database. The valine at codon 393 is highly conserved, and computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.66). Due to limited information, the clinical significance of the p.Val393Ile variant is uncertain at this time. Gene specific statement: Pathogenic variants in FKRP are inherited in an autosomal recessive manner and are associated with muscular dystrophy-dystroglycanopathy types A5, B5 and C5 (MIM: 613153, 606612, and 607155). Symptomatic heterozygous carriers have also been reported at least once in the literature and present with a milder phenotype (Schottlaender et al. 2015).
Ambry Genetics	RCV002336274	SCV002639713	benign	Cardiovascular phenotype	2019-01-29	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
