Genes affected

CARF (HGNC:14435): (calcium responsive transcription factor) Enables DNA binding activity and DNA-binding transcription factor activity. Involved in cellular response to potassium ion and positive regulation of transcription from RNA polymerase II promoter in response to calcium ion. Predicted to be located in granular component. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

WDR12 (HGNC:14098): (WD repeat domain 12) This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. This protein is highly similar to the mouse WD repeat domain 12 protein at the amino acid level. The protein encoded by this gene is a component of a nucleolar protein complex that affects maturation of the large ribosomal subunit.[provided by RefSeq, Dec 2008]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
