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.

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.37868133).

Apr 16, 2024

The c.598C>G (p.P200A) alteration is located in exon 3 (coding exon 3) of the CRIM1 gene. This alteration results from a C to G substitution at nucleotide position 598, causing the proline (P) at amino acid position 200 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
