Variant summary

Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM1 PM2 PP5

The NM_003839.4(TNFRSF11A):c.49_63dup(p.Leu17_Leu21dup) variant causes a inframe insertion change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (no stars). Synonymous variant affecting the same amino acid position (i.e. L16L) has been classified as Likely benign.

Genes affected

TNFRSF11A (HGNC:11908): (TNF receptor superfamily member 11a) The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptors can interact with various TRAF family proteins, through which this receptor induces the activation of NF-kappa B and MAPK8/JNK. This receptor and its ligand are important regulators of the interaction between T cells and dendritic cells. This receptor is also an essential mediator for osteoclast and lymph node development. Mutations at this locus have been associated with familial expansile osteolysis, autosomal recessive osteopetrosis, and Paget disease of bone. Alternatively spliced transcript variants have been described for this locus. [provided by RefSeq, Aug 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM1: In a signal_peptide (size 28) in uniprot entity TNR11_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_003839.4
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 18-62325400-G-GCTCTGCGCGCTGCTC is Pathogenic according to our data. Variant chr18-62325400-G-GCTCTGCGCGCTGCTC is described in ClinVar as [Pathogenic]. Clinvar id is 208144.Status of the report is no_assertion_criteria_provided, 0 stars.
