Genes affected

STAMBP (HGNC:16950): (STAM binding protein) Cytokine-mediated signal transduction in the JAK-STAT cascade requires the involvement of adaptor molecules. One such signal-transducing adaptor molecule contains an SH3 domain that is required for induction of MYC and cell growth. The protein encoded by this gene binds to the SH3 domain of the signal-transducing adaptor molecule, and plays a critical role in cytokine-mediated signaling for MYC induction and cell cycle progression. Multiple alternatively spliced transcript variants encoding the same protein isoform have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM1

In a region_of_interest Interaction with CHMP3 (size 126) in uniprot entity STABP_HUMAN there are 11 pathogenic changes around while only 1 benign (92%) in NM_213622.4

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.0862408).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000526 (8/152196) while in subpopulation EAS AF= 0.00135 (7/5192). AF 95% confidence interval is 0.000632. There are 0 homozygotes in gnomad4. There are 1 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 10 of the STAMBP protein (p.Pro10Leu). This variant is present in population databases (rs767316172, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with STAMBP-related conditions. ClinVar contains an entry for this variant (Variation ID: 1412908). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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. -
