Genes affected

USP48 (HGNC:18533): (ubiquitin specific peptidase 48) This gene encodes a protein containing domains that associate it with the peptidase family C19, also known as family 2 of ubiquitin carboxyl-terminal hydrolases. Family members function as deubiquitinating enzymes, recognizing and hydrolyzing the peptide bond at the C-terminal glycine of ubiquitin. Enzymes in peptidase family C19 are involved in the processing of poly-ubiquitin precursors as well as that of ubiquitinated proteins. 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 -6 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), USP48. . Gene score misZ 4.3729 (greater than the threshold 3.09). Trascript score misZ 4.4487 (greater than threshold 3.09). GenCC has associacion of gene with schizophrenia, hearing loss, autosomal dominant 85.

BP4

Computational evidence support a benign effect (MetaRNN=0.034331888).

BP6

Variant 1-21704318-G-A is Benign according to our data. Variant chr1-21704318-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3187722.Status of the report is criteria_provided_single_submitter, 1 stars.

BS2

High AC in GnomAd4 at 9 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Ambry Genetics

Dec 21, 2023

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
