Genes affected

GDF3 (HGNC:4218): (growth differentiation factor 3) This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein plays a role ocular and skeletal development. Mutations in this gene are associated with microphthalmia, coloboma, and skeletal abnormalities in human patients. [provided by RefSeq, Aug 2016]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr12-7690059-A-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 423808.Status of the report is criteria_provided_single_submitter, 1 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.19572407).

BP6

Variant 12-7690059-A-G is Benign according to our data. Variant chr12-7690059-A-G is described in ClinVar as Benign. ClinVar VariationId is 30592.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS2

High AC in GnomAd4 at 16 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
