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]

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]

ACMG classification

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.98
