Genes affected

ACVR1C (HGNC:18123): (activin A receptor type 1C) ACVR1C is a type I receptor for the TGFB (see MIM 190180) family of signaling molecules. Upon ligand binding, type I receptors phosphorylate cytoplasmic SMAD transcription factors, which then translocate to the nucleus and interact directly with DNA or in complex with other transcription factors (Bondestam et al., 2001 [PubMed 12063393]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0019722283).
• BP6: Variant 2-157533956-T-C is Benign according to our data. Variant chr2-157533956-T-C is described in ClinVar as [Benign]. Clinvar id is 1282954.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.37 is higher than 0.05.
