Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_001353258.2(CYRIB):c.523G>A(p.Gly175Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000604 in 1,556,668 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).
CYRIB (HGNC:25216): (CYFIP related Rac1 interactor B) Enables small GTPase binding activity. Involved in several processes, including cellular response to molecule of bacterial origin; negative regulation of small GTPase mediated signal transduction; and regulation of organelle organization. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]
Review Status: criteria provided, single submitter
Collection Method: clinical testing
The c.523G>A (p.G175R) alteration is located in exon 11 (coding exon 6) of the FAM49B gene. This alteration results from a G to A substitution at nucleotide position 523, causing the glycine (G) at amino acid position 175 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
