Genes affected

RORC (HGNC:10260): (RAR related orphan receptor C) The protein encoded by this gene is a DNA-binding transcription factor and is a member of the NR1 subfamily of nuclear hormone receptors. The specific functions of this protein are not known; however, studies of a similar gene in mice have shown that this gene may be essential for lymphoid organogenesis and may play an important regulatory role in thymopoiesis. In addition, studies in mice suggest that the protein encoded by this gene may inhibit the expression of Fas ligand and IL2. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

RORC Gene-Disease associations (from GenCC):

• autosomal recessive mendelian susceptibility to mycobacterial diseases due to complete RORgamma receptor deficiency

ACMG classification

Our verdict: Likely_benign. The variant received -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000132 (2/151892) while in subpopulation SAS AF = 0.000415 (2/4820). AF 95% confidence interval is 0.000073. There are 0 homozygotes in GnomAd4. There are 2 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
