Neurogenetics, Cyprus Institute of Neurology and Genetics RCV001814583 SCV001759935 likely pathogenic Ceroid lipofuscinosis, neuronal, 6A 2021-07-20 criteria provided, single submitter clinical testing CLN6 c.884A>G sequence change replaces Tyrosine with Cysteine at codon 295 of the CLN6 protein (p. Tyr295Cys). Tyrosine is an aromatic highly conserved amino acid and there is a physicochemical difference between Tyrosine and Cysteine. This variant has been observed as de novo along with a known pathogenic variant, in an individual with clinical features of neuronal ceroid lipofuscinosis thus supporting the pathogenicity of this variant. In silico, prediction analysis (SIFT, PolyPhen-2, MutationTaster, VarCards) showed that this variant is Likely Pathogenic. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
