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]

SPOP Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with microcephaly and dysmorphic facies

• neurodevelopmental disorder with relative macrocephaly and with or without cardiac or endocrine anomalies

  Inheritance: AD Classification: STRONG Submitted by: G2P

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.204 is higher than 0.05.
