Genes affected

FRAS1 (HGNC:19185): (Fraser extracellular matrix complex subunit 1) This gene encodes an extracellular matrix protein that appears to function in the regulation of epidermal-basement membrane adhesion and organogenesis during development. Mutations in this gene cause Fraser syndrome, a multisystem malformation that can include craniofacial, urogenital and respiratory system abnormalities. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Nov 27, 2023	This sequence change creates a premature translational stop signal (p.Tyr2517*) in the FRAS1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in FRAS1 are known to be pathogenic (PMID: 12766769, 18671281). This variant is present in population databases (rs745597204, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with Fraser syndrome (PMID: 18671281). ClinVar contains an entry for this variant (Variation ID: 235484). For these reasons, this variant has been classified as Pathogenic. -

This individual is heterozygous for the c.7551T>A variant in the FRAS1 gene. This variant creates a premature stop codon p.(Tyr2517*) and may result in a null allele due to nonsense-mediated mRNA decay. This variant has been reported in the gnomAD browser (http://gnomad.broadinstitute.org) with a very low allele frequency of 0.002% (5 out of 244, 500 alleles). The variant has been previously reported in a patient with Fraser syndrome (Haelst et al Am J Med Genet A. 2008 Sep 1;146A(17):2252-2257) and has also been listed on ClinVar to be pathogenic (https://www.ncbi.nlm.nih.gov/clinvar/variation/235484/). This variant is considered to be a pathogenic according to the ACMG guidelines. (Evidence used: PVS1, PM2, PP5). -
