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.

  • colobomatous macrophthalmia-microcornea syndrome
    Inheritance: AD, Unknown Classification: SUPPORTIVE, LIMITED Submitted by: Orphanet, Labcorp Genetics (formerly Invitae)

The c.639C>A (p.N213K) alteration is located in exon 3 (coding exon 3) of the CRIM1 gene. This alteration results from a C to A substitution at nucleotide position 639, causing the asparagine (N) at amino acid position 213 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
