Genes affected
MPZL2 (HGNC:3496): (myelin protein zero like 2) Thymus development depends on a complex series of interactions between thymocytes and the stromal component of the organ. Epithelial V-like antigen (EVA) is expressed in thymus epithelium and strongly downregulated by thymocyte developmental progression. This gene is expressed in the thymus and in several epithelial structures early in embryogenesis. It is highly homologous to the myelin protein zero and, in thymus-derived epithelial cell lines, is poorly soluble in nonionic detergents, strongly suggesting an association to the cytoskeleton. Its capacity to mediate cell adhesion through a homophilic interaction and its selective regulation by T cell maturation might imply the participation of EVA in the earliest phases of thymus organogenesis. The protein bears a characteristic V-type domain and two potential N-glycosylation sites in the extracellular domain; a putative serine phosphorylation site for casein kinase 2 is also present in the cytoplasmic tail. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PP3
Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, Cadd, Eigen, MutationAssessor, phyloP100way_vertebrate, PROVEAN, REVEL, REVEL [when BayesDel_addAF, max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]
PP5
Variant 11-118262488-G-C is Pathogenic according to our data. Variant chr11-118262488-G-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 1216057.
BP4
Computational evidence support a benign effect (MetaRNN=0.33456525). . Strength limited to SUPPORTING due to the PP5.
