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]

Sep 14, 2021

The c.482C>G (p.T161S) alteration is located in exon 3 (coding exon 3) of the CBLN3 gene. This alteration results from a C to G substitution at nucleotide position 482, causing the threonine (T) at amino acid position 161 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
