Genes affected
PLP1 (HGNC:9086): (proteolipid protein 1) This gene encodes a transmembrane proteolipid protein that is the predominant component of myelin. The encoded protein may play a role in the compaction, stabilization, and maintenance of myelin sheaths, as well as in oligodendrocyte development and axonal survival. Mutations in this gene cause Pelizaeus-Merzbacher disease and spastic paraplegia type 2. Alternatively splicing results in multiple transcript variants, including the DM20 splice variant.

ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 8 ACMG points.
PM1
?
In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_000533.5
PM2
?
Very rare variant in population databases, with high coverage;
PP3
?
Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
PP5
?
Variant X-103787961-T-G is Pathogenic according to our data. Variant chrX-103787961-T-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 496683.Status of the report is criteria_provided_single_submitter, 1 stars.
