Genes affected

RCOR1 (HGNC:17441): (REST corepressor 1) This gene encodes a protein that is well-conserved, downregulated at birth, and with a specific role in determining neural cell differentiation. The encoded protein binds to the C-terminal domain of REST (repressor element-1 silencing transcription factor). [provided by RefSeq, Aug 2011]

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

BP3

Nonframeshift variant in repetitive region in NM_015156.4

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.00122 (179/146844) while in subpopulation SAS AF= 0.0333 (159/4776). AF 95% confidence interval is 0.0291. There are 4 homozygotes in gnomad4. There are 132 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 179 AD gene.

This variant, c.88_90dup, results in the insertion of 1 amino acid(s) of the RCOR1 protein (p.Ala30dup), but otherwise preserves the integrity of the reading frame. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with RCOR1-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
