Genes affected
EMCN (HGNC:16041): (endomucin) EMCN is a mucin-like sialoglycoprotein that interferes with the assembly of focal adhesion complexes and inhibits interaction between cells and the extracellular matrix (Kinoshita et al., 2001 [PubMed 11418125]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2023The c.377C>A (p.T126N) alteration is located in exon 5 (coding exon 5) of the EMCN gene. This alteration results from a C to A substitution at nucleotide position 377, causing the threonine (T) at amino acid position 126 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
