Genes affected

CRIM1 (HGNC:2359): (cysteine rich transmembrane BMP regulator 1) This gene encodes a transmembrane protein containing six cysteine-rich repeat domains and an insulin-like growth factor-binding domain. The encoded protein may play a role in tissue development though interactions with members of the transforming growth factor beta family, such as bone morphogenetic proteins.

Collection Method: clinical testing

The c.655C>T (p.R219C) alteration is located in exon 3 (coding exon 3) of the CRIM1 gene. This alteration results from a C to T substitution at nucleotide position 655, causing the arginine (R) at amino acid position 219 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
