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]

This sequence change creates a premature translational stop signal (p.Val2322Glyfs*6) 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 (rs730882179, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with clinical features of FRAS1-related conditions (PMID: 16894541, 31999076). This variant is also known as 6992insGG. ClinVar contains an entry for this variant (Variation ID: 2815). For these reasons, this variant has been classified as Pathogenic. -
