Genes affected

RCBTB1 (HGNC:18243): (RCC1 and BTB domain containing protein 1) This gene encodes a protein with an N-terminal RCC1 domain and a C-terminal BTB (broad complex, tramtrack and bric-a-brac) domain. In rat, over-expression of this gene in vascular smooth muscle cells induced cellular hypertrophy. In rat, the C-terminus of RCBTB1 interacts with the angiotensin II receptor-1A. In humans, this gene maps to a region of chromosome 13q that is frequently deleted in B-cell chronic lymphocytic leukemia and other lymphoid malignancies. [provided by RefSeq, Jul 2008]

This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 401 of the RCBTB1 protein (p.Ser401Leu). This variant is present in population databases (rs556664001, gnomAD 0.009%). This missense change has been observed in individual(s) with retinal dystrophy (PMID: 27486781). ClinVar contains an entry for this variant (Variation ID: 253021). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RCBTB1 protein function with a negative predictive value of 80%. 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. -
