Rett and Angelman-like Disorders VCEP

The p.Asp193Gly variant in CDKL5 has been reported in at least 2 de novo occurrences (biological parentage unconfirmed) in affected individuals (PMID 23583054) (PM6_Strong). The p.Asp193Gly variant in CDKL5 is absent from gnomAD (PM2_Supporting). The variant has been reported to segregate in two informative meioses (PMID: 23583054) (PP1). Computational prediction analysis tools suggests a deleterious impact; however, this information does not predict clinical significance on its own (PP3). The p.Asp193Gly variant in CDKL5 has been reported in an individual with a clinical phenotype suggestive of a CDKL5-associated disorder (PP4). In summary, the p.Asp193Gly variant in CDKL5 is classified as likely pathogenic for CDKL5-associated disorder based on the ACMG/AMP criteria (PM6_strong, PM2_supporting, PP1, PP3, PP4).

PP1

The variant has been reported to segregate in two informative meioses (PMID: 23583054)

The p.Asp193Gly variant has been reported to segregate in two affected family members with CDKL5 disorder. PubMed:23583054

PP4

The p.Asp193Gly variant in CDKL5 has been reported in an individual with a clinical phenotype suggestive of a CDKL5-associated disorder

PP3

Computational prediction analysis tools suggests a deleterious impact; however, this information does not predict clinical significance on its own

PM6_Strong

The p.Asp193Gly variant in CDKL5 has been reported in at least 2 de novo occurrences (biological parentage unconfirmed) in affected individuals (PMID 23583054)

PM2_Supporting

The p.Asp193Gly variant in CDKL5 is absent from gnomAD.

PM5

Multiple missense variants have been previously identified within this codon (p.Asp193His and p.Asp193Asn); however these sequence variants do not meet the classification of pathogenic (PMID 27781031, 29655203).
