dbSNP rs2293277: CEP55:p.His378Pro (chr10-93519749-A-C) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_018131.5(CEP55):c.1133A>C(p.His378Pro) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,461,788 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H378L) has been classified as Benign.

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]
