Genes affected

CBLN3 (HGNC:20146): (cerebellin 3 precursor) Members of the precerebellin family, such as CBLN3, contain a cerebellin motif (see CBLN1; MIM 600432) and a C-terminal C1q signature domain (see MIM 120550) that mediates trimeric assembly of atypical collagen complexes. However, precerebellins do not contain a collagen motif, suggesting that they are not conventional components of the extracellular matrix (Pang et al., 2000 [PubMed 10964938]).[supplied by OMIM, Aug 2009]

CBLN3 links:

KHNYN (HGNC:20166): (KH and NYN domain containing) The protein encoded by this gene contains a ribonuclease NYN domain and belongs to the N4BP1 family. The protein is a cofactor for the zinc finger antiviral protein (ZAP protein) which targets viral RNA for degradation and restricts SARS-CoV-2 infection. [provided by RefSeq, Sep 2021]

The c.176C>T (p.P59L) alteration is located in exon 1 (coding exon 1) of the CBLN3 gene. This alteration results from a C to T substitution at nucleotide position 176, causing the proline (P) at amino acid position 59 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
