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

Verdict is Likely_benign. Variant got -4 ACMG points.

• BS2: High AC in GnomAdExome4 at 6 AD gene.

Aug 22, 2023

The c.138G>T (p.W46C) alteration is located in exon 1 (coding exon 1) of the BICC1 gene. This alteration results from a G to T substitution at nucleotide position 138, causing the tryptophan (W) at amino acid position 46 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
