Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BA1BP7

This summary comes from the ClinGen Evidence Repository: The allele frequency of the p.Ser815= variant in CDKL5 is 0.1% in African sub population in gnomAD, which is high enough to be classified as benign based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BA1). The silent p.Ser815= variant is not predicted to affect splicing using multiple computational tools and does not affect a highly conserved nucleotide (BP7). In summary, the p.Ser815= variant in CDKL5 is classified as benign based on the ACMG/AMP criteria (BA1, BP7). LINK:https://erepo.genome.network/evrepo/ui/classification/CA10360539/MONDO:0100039/016

Genes affected
CDKL5 (HGNC:11411): (cyclin dependent kinase like 5) This gene is a member of Ser/Thr protein kinase family and encodes a phosphorylated protein with protein kinase activity. Mutations in this gene have been associated with X-linked infantile spasm syndrome (ISSX), also known as X-linked West syndrome, and Rett syndrome (RTT). Alternate transcriptional splice variants have been characterized. [provided by RefSeq, Jul 2008]
