Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_014781.5(RB1CC1):ā€‹c.3646A>Gā€‹(p.Arg1216Gly) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,554 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1216K) has been classified as Likely benign.

Genes affected
RB1CC1 (HGNC:15574): (RB1 inducible coiled-coil 1) The protein encoded by this gene interacts with signaling pathways to coordinately regulate cell growth, cell proliferation, apoptosis, autophagy, and cell migration. This tumor suppressor also enhances retinoblastoma 1 gene expression in cancer cells. Alternative splicing results in multiple transcript variants encoding distinct isoforms.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 28, 2023The c.3646A>G (p.R1216G) alteration is located in exon 15 (coding exon 13) of the RB1CC1 gene. This alteration results from a A to G substitution at nucleotide position 3646, causing the arginine (R) at amino acid position 1216 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
