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 Likely_benign. Variant got -5 ACMG points.

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). The gene has 24 curated pathogenic missense variants (we use a threshold of 10). The gene has 36 curated benign missense variants. GenCC has associacion of the 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.

BP4

Computational evidence support a benign effect (MetaRNN=0.1865552).

This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 4 of the USP9X protein (p.Thr4Ala). This variant is present in population databases (rs775400408, gnomAD 0.03%), including at least one homozygous and/or hemizygous individual. This missense change has been observed in individual(s) with autism spectrum disorder (PMID: 33023636). 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. -
