Genes affected

UBA1 (HGNC:12469): (ubiquitin like modifier activating enzyme 1) The protein encoded by this gene catalyzes the first step in ubiquitin conjugation to mark cellular proteins for degradation. This gene complements an X-linked mouse temperature-sensitive defect in DNA synthesis, and thus may function in DNA repair. It is part of a gene cluster on chromosome Xp11.23. Alternatively spliced transcript variants that encode the same protein have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant X-47196470-G-A is Benign according to our data. Variant chrX-47196470-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 2660404.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High Hemizygotes in GnomAd4 at 6 XL gene
