Genes affected
MALT1 (HGNC:6819): (MALT1 paracaspase) This gene encodes a caspase-like protease that plays a role in BCL10-induced activation of NF-kappaB. The protein is a component of the CARMA1-BCL10-MALT1 (CBM) signalosome that triggers NF-kappaB signaling and lymphoctye activation following antigen-receptor stimulation. Mutations in this gene result in immunodeficiency 12 (IMD12). This gene has been found to be recurrently rearranged in chromosomal translocations with other genes in mucosa-associated lymphoid tissue lymphomas, including a t(11;18)(q21;q21) translocation with the baculoviral IAP repeat-containing protein 3 (also known as apoptosis inhibitor 2) locus [BIRC3(API2)-MALT1], and a t(14;18)(q32;q21) translocation with the immunoglobulin heavy chain locus (IGH-MALT1). Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, May 2018]

Likely benign, criteria provided, single submitterclinical testingAl Jalila Children’s Genomics Center, Al Jalila Childrens Speciality HospitalOct 06, 2020- -
Uncertain significance, criteria provided, single submitterclinical testingInvitaeDec 18, 2023This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 428 of the MALT1 protein (p.Val428Ile). This variant is present in population databases (rs140664950, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with MALT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 572153). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt MALT1 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
