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]
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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.131A>C (p.E44A) alteration is located in exon 1 (coding exon 1) of the CBLN3 gene. This alteration results from a A to C substitution at nucleotide position 131, causing the glutamic acid (E) at amino acid position 44 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
