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]

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.48).

BP6

Variant X-47202718-C-T is Benign according to our data. Variant chrX-47202718-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 368333.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-1.6 with no splicing effect.

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000455 (499/1097387) while in subpopulation MID AF = 0.0247 (102/4132). AF 95% confidence interval is 0.0208. There are 6 homozygotes in GnomAdExome4. There are 174 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Hemizygotes in GnomAd4 at 13 XL,Unknown gene
