Genes affected

CEP55 (HGNC:1161): (centrosomal protein 55) Enables identical protein binding activity. Involved in cranial skeletal system development; establishment of protein localization; and midbody abscission. Acts upstream of or within mitotic cytokinesis. Located in Flemming body; centriolar satellite; and plasma membrane. Implicated in multinucleated neurons, anhydramnios, renal dysplasia, cerebellar hypoplasia and hydranencephaly. [provided by Alliance of Genome Resources, Apr 2022]

The c.257G>A (p.R86Q) alteration is located in exon 3 (coding exon 2) of the CEP55 gene. This alteration results from a G to A substitution at nucleotide position 257, causing the arginine (R) at amino acid position 86 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
