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

Jun 07, 2024

The c.1151T>C (p.I384T) alteration is located in exon 5 (coding exon 4) of the ECM2 gene. This alteration results from a T to C substitution at nucleotide position 1151, causing the isoleucine (I) at amino acid position 384 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
