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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the USP9X gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 24 curated pathogenic missense variants (we use a threshold of 10). The gene has 36 curated benign missense variants. Gene score misZ: 6.4105 (above the threshold of 3.09). GenCC associations: The gene is linked to 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.

BP4

Computational evidence support a benign effect (MetaRNN=0.25120467).

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 26 of the USP9X protein (p.Pro26Leu). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with USP9X-related conditions. ClinVar contains an entry for this variant (Variation ID: 1938884). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
