Genes affected

TLL2 (HGNC:11844): (tolloid like 2) This gene encodes an astacin-like zinc-dependent metalloprotease and is a subfamily member of the metzincin family. Unlike other family members, a similar protein in mice does not cleave procollagen C-propeptides or chordin. [provided by RefSeq, Jul 2008]

ENSG00000310117 (HGNC:):

ACMG classification
