Variant summary

Our verdict is Benign. The variant received -17 ACMG points: 0P and 17B. BP3 BP6_Very_Strong BA1

The NM_001024630.4(RUNX2):​c.243_260delGGCGGCTGCGGCGGCGGC​(p.Ala82_Ala87del) variant causes a disruptive inframe deletion change. The variant allele was found at a frequency of 0.0616 in 1,529,834 control chromosomes in the GnomAD database, including 9,156 homozygotes. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Likely benign (★★).

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]
