Genes affected

CARD14 (HGNC:16446): (caspase recruitment domain family member 14) This gene encodes a caspase recruitment domain-containing protein that is a member of the membrane-associated guanylate kinase (MAGUK) family of proteins. Members of this protein family are scaffold proteins that are involved in a diverse array of cellular processes including cellular adhesion, signal transduction and cell polarity control. This protein has been shown to specifically interact with BCL10, a protein known to function as a positive regulator of cell apoptosis and NF-kappaB activation. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Apr 2012]

CARD14 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

Pathogenic, no assertion criteria provided	literature only	OMIM	May 04, 2012	- -
Pathogenic, criteria provided, single submitter	clinical testing	Victorian Clinical Genetics Services, Murdoch Childrens Research Institute	May 25, 2020	Based on the classification scheme VCGS_Germline_v1.1.1, this variant is classified as pathogenic. Following criteria are met: 0101 - Gain-of-function is a known mechanism of disease for this gene. (N) 0107 - This gene is known to be associated with autosomal dominant disease. (N) 0210 - Splice site variant (non-canonical) proven to affect splicing of the transcript, resulting in the use of a cryptic splice site in intron 3 (PMID:22521418). (N) 0213 - In-frame insertion of 22 amino acids into the protein between exon 3 and exon 4. (P) 0251 - Variant is heterozygous. (N) 0301 - Variant is absent from gnomAD. (P) 0505 - Abnormal splicing is predicted by in silico tools and the affected nucleotide is highly conserved. (P) 0703 - Comparable variants (c.349+5G>C, c.349+1G>A, p.Gly117Ser) also functionally proven to impact splicing and cause the same in-frame intron retention, have moderate previous evidence for pathogenicity (ClinVar, PMID:22521418, PMID:29477734). (P) 0803 - Low previous evidence of pathogenicity in a single large family with psoriasis (ClinVar, PMID:22521418). (P) 0901 - Strong evidence for segregation with disease in a single very large family (PMID:22521418). (P) 1007 - No published functional evidence has been identified for this variant. (N) 1208 - Inheritance information for this variant is not currently available. (N) Legend: (P) - Pathogenic, (N) - Neutral, (B) - Benign -
