Genes affected
YY1AP1 (HGNC:30935): (YY1 associated protein 1) Predicted to enable transcription coregulator activity. Involved in cell differentiation; cell population proliferation; and regulation of cell cycle. Located in fibrillar center and nucleoplasm. Colocalizes with Ino80 complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 18 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 5.1, offset of 4, new splice context is: tgtcgtgttttcccaaaaAGagc. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 1-155672732-C-T is Pathogenic according to our data. Variant chr1-155672732-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 523660.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Pathogenic, criteria provided, single submitterin vitroInstitute of Human Genetics Greifswald, Research Division, University Medicine GreifswaldMay 02, 2018The c.826-1G>A variant in YY1AP1 has been identified in a compound heterozygous state with another YY1AP1 splice mutation. Additionally, RT-PCR on RNA from blood lymphocytes confirmed skipping of exon 6 which causes a frameshift. In summary, the c.826-1G>A variant meets the ACMG criteria to be classified as pathogenic based upon segregation studies, population frequency data and functional evidence. -
