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 Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), USP9X. . Gene score misZ 6.4105 (greater than the threshold 3.09). GenCC has associacion of gene with non-syndromic X-linked intellectual disability, X-linked syndromic intellectual disability, intellectual disability, X-linked 99, syndromic, female-restricted, intellectual disability, X-linked 99, X-linked female restricted facial dysmorphism-short stature-choanal atresia-intellectual disability.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.867
