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]

Ambry Genetics

Apr 23, 2024

The c.2478C>G (p.H826Q) alteration is located in exon 19 (coding exon 19) of the TLL2 gene. This alteration results from a C to G substitution at nucleotide position 2478, causing the histidine (H) at amino acid position 826 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
