Genes affected

USP9X (HGNC:12632): (ubiquitin specific peptidase 9 X-linked) This gene is a member of the peptidase C19 family and encodes a protein that is similar to ubiquitin-specific proteases. Though this gene is located on the X chromosome, it escapes X-inactivation. Mutations in this gene have been associated with Turner syndrome. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant X-41151058-G-A is Pathogenic according to our data. Variant chrX-41151058-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 521453.Status of the report is criteria_provided_single_submitter, 1 stars.
