Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_139119.3(YY1AP1):​c.2073A>T​(p.Gly691Gly) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. G691G) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: YY1AP1 NM_139119.3 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.56

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]

ENSG00000246203 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.69).
• BP7: Synonymous conserved (PhyloP=-1.57 with no splicing effect.
