Our verdict is Benign. Variant got -11 ACMG points: 0P and 11B. BP4_ModerateBP7BS1BS2

The NM_001024630.4(RUNX2):​c.240G>T​(p.Ala80Ala) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000598 in 1,336,792 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. A80A) has been classified as 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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -11 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.4).
BP7
Synonymous conserved (PhyloP=0.758 with no splicing effect.
BS1
Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.00000598 (8/1336792) while in subpopulation EAS AF= 0.000196 (6/30582). AF 95% confidence interval is 0.0000852. There are 0 homozygotes in gnomad4_exome. There are 2 alleles in male gnomad4_exome subpopulation. Median coverage is 35. This position pass quality control queck.
BS2
High AC in GnomAdExome4 at 8 AD gene.
