Genes affected

ECM2 (HGNC:3154): (extracellular matrix protein 2) ECM2 encodes extracellular matrix protein 2, so named because it shares extensive similarity with known extracelluar matrix proteins. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2010]

ECM2 links:

CENPP (HGNC:32933): (centromere protein P) CENPP is a subunit of a CENPH (MIM 605607)-CENPI (MIM 300065)-associated centromeric complex that targets CENPA (MIM 117139) to centromeres and is required for proper kinetochore function and mitotic progression (Okada et al., 2006 [PubMed 16622420]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Dec 07, 2021

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
