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 GeneticsJun 01, 2023The c.244A>G (p.T82A) alteration is located in exon 3 (coding exon 3) of the EMCN gene. This alteration results from a A to G substitution at nucleotide position 244, causing the threonine (T) at amino acid position 82 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
