Baylor Miraca Genetics Laboratories, RCV000009000 SCV000807237 pathogenic Niemann-Pick disease type C2 2017-09-01 criteria provided, single submitter clinical testing This variant has been previously reported as disease-causing and was found once in our laboratory homozygous in a 14-year-old male with intellectual disability, epilepsy, similarly affected sibling
Invitae RCV000009000 SCV000953622 likely pathogenic Niemann-Pick disease type C2 2018-10-29 criteria provided, single submitter clinical testing This sequence change falls in intron 2 of the NPC2 gene. It does not directly change the encoded amino acid sequence of the NPC2 protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is present in population databases (rs80358268, ExAC 0.1%). This variant has been observed in individuals affected with Niemann-Pick type C disease (PMID: 11567215, 28105569). It is also known as IVS2+5G>A in the literature. ClinVar contains an entry for this variant (Variation ID: 8479). Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Experimental studies have shown that this variant disrupts mRNA splicing (PMID: 11567215). 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.
