Genes affected

RUNX2 (HGNC:10472): (RUNX family transcription factor 2) This gene is a member of the RUNX family of transcription factors and encodes a nuclear protein with an Runt DNA-binding domain. This protein is essential for osteoblastic differentiation and skeletal morphogenesis and acts as a scaffold for nucleic acids and regulatory factors involved in skeletal gene expression. The protein can bind DNA both as a monomer or, with more affinity, as a subunit of a heterodimeric complex. Two regions of potential trinucleotide repeat expansions are present in the N-terminal region of the encoded protein, and these and other mutations in this gene have been associated with the bone development disorder cleidocranial dysplasia (CCD). Transcript variants that encode different protein isoforms result from the use of alternate promoters as well as alternate splicing. [provided by RefSeq, Jul 2016]

SUPT3H (HGNC:11466): (SPT3 homolog, SAGA and STAGA complex component) Enables transcription coactivator activity. Involved in histone H3 acetylation and histone deubiquitination. Located in nucleoplasm. Part of SAGA complex and transcription factor TFTC complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.63).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.247 is higher than 0.05.
