Genes affected

FZR1 (HGNC:24824): (fizzy and cell division cycle 20 related 1) Predicted to enable anaphase-promoting complex binding activity and ubiquitin ligase activator activity. Involved in anaphase-promoting complex-dependent catabolic process; mitotic G2 DNA damage checkpoint signaling; and positive regulation of protein metabolic process. Located in nuclear membrane and nucleoplasm. Colocalizes with anaphase-promoting complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.224G>A (p.R75Q) alteration is located in exon 3 (coding exon 3) of the FZR1 gene. This alteration results from a G to A substitution at nucleotide position 224, causing the arginine (R) at amino acid position 75 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
