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]
DAP3 (HGNC:2673): (death associated protein 3) Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. This gene encodes a 28S subunit protein that also participates in apoptotic pathways which are initiated by tumor necrosis factor-alpha, Fas ligand, and gamma interferon. This protein potentially binds ATP/GTP and might be a functional partner of the mitoribosomal protein S27. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. Pseudogenes corresponding to this gene are found on chromosomes 1q and 2q.

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 08, 2017For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in YY1AP1 are known to be pathogenic (PMID: 27939641). This variant has not been reported in the literature in individuals with YY1AP1-related disease. This variant is present in population databases (rs778715969, ExAC 0.02%). This sequence change creates a premature translational stop signal (p.Gly56Argfs*42) in the YY1AP1 gene. It is expected to result in an absent or disrupted protein product. -
