Spondylometaphyseal dysplasia Pathogenic:1
6 Individuals with novel FN1 mutations and spondylometaphyseal dysplasia -
Spondylometaphyseal dysplasia - Sutcliffe type Pathogenic:1
This variant is interpreted as Likely Pathogenic, for Spondylometaphyseal dysplasia, corner fracture type, autosomal dominant. The following ACMG Tag(s) were applied: PM6 => Assumed de novo, but without confirmation of paternity and maternity (https://www.ncbi.nlm.nih.gov/pubmed/29100092). PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PM1 => Located in a mutational hot spot and/or critical and well-established functional domain (e.g., active site of an enzyme) without benign variation. Replaces a cysteine involved in disulfide bond. (http://www.uniprot.org/uniprot/P02751). PS3-Moderate => PS3 downgraded in strength to Moderate. -
