Genes affected

SPOP (HGNC:11254): (speckle type BTB/POZ protein) This gene encodes a protein that may modulate the transcriptional repression activities of death-associated protein 6 (DAXX), which interacts with histone deacetylase, core histones, and other histone-associated proteins. In mouse, the encoded protein binds to the putative leucine zipper domain of macroH2A1.2, a variant H2A histone that is enriched on inactivated X chromosomes. The BTB/POZ domain of this protein has been shown in other proteins to mediate transcriptional repression and to interact with components of histone deacetylase co-repressor complexes. Alternative splicing of this gene results in multiple transcript variants encoding the same protein. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM1: In a region_of_interest Required for nuclear localization (size 120) in uniprot entity SPOP_HUMAN there are 5 pathogenic changes around while only 0 benign (100%) in NM_001007228.2
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SPOP. . Trascript score misZ 5.5316 (greater than threshold 3.09). GenCC has associacion of gene with neurodevelopmental disorder with microcephaly and dysmorphic facies.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.747
