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

Sep 15, 2021

The c.2525G>A (p.S842N) alteration is located in exon 19 (coding exon 19) of the TLL2 gene. This alteration results from a G to A substitution at nucleotide position 2525, causing the serine (S) at amino acid position 842 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
