Genes affected

CEP152 (HGNC:29298): (centrosomal protein 152) This gene encodes a protein that is thought to be involved with centrosome function. Mutations in this gene have been associated with primary microcephaly (MCPH4). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2010]

The CEP152 c.4963T>A (p.Ter1655LysextTer6) variant is a stop-lost variant. A literature search was performed for the gene, cDNA change, and amino acid change. No publications were found based on this search. Based on the variant frequency, disease prevalence, disease penetrance, and inheritance mode, this variant could not be ruled out of causing disease. Due to the potential impact of stop-lost variants and the lack of clarifying evidence, this variant is classified as a variant of unknown significance but suspicious for pathogenicity for CEP152-related disorders. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -
