Genes affected

BICC1 (HGNC:19351): (BicC family RNA binding protein 1) This gene encodes an RNA-binding protein that is active in regulating gene expression by modulating protein translation during embryonic development. Mouse studies identified the corresponding protein to be under strict control during cell differentiation and to be a maternally provided gene product. [provided by RefSeq, Apr 2009]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.09405455).

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.00000279 (4/1432728) while in subpopulation EAS AF= 0.0000824 (3/36390). AF 95% confidence interval is 0.0000219. There are 0 homozygotes in gnomad4_exome. There are 2 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. This variant has not been reported in the literature in individuals affected with BICC1-related conditions. This sequence change replaces serine with leucine at codon 14 of the BICC1 protein (p.Ser14Leu). The serine residue is weakly conserved and there is a large physicochemical difference between serine and leucine. This variant is present in population databases (rs769280220, ExAC 0.01%). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). -
