Genes affected
ALG13 (HGNC:30881): (ALG13 UDP-N-acetylglucosaminyltransferase subunit) The protein encoded by this gene is a subunit of a bipartite UDP-N-acetylglucosamine transferase. It heterodimerizes with asparagine-linked glycosylation 14 homolog to form a functional UDP-GlcNAc glycosyltransferase that catalyzes the second sugar addition of the highly conserved oligosaccharide precursor in endoplasmic reticulum N-linked glycosylation. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2009]

BP6
Variant X-111759984-A-G is Benign according to our data. Variant chrX-111759984-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 512702.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.012 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000448 (50/111517) while in subpopulation AFR AF= 0.00153 (47/30627). AF 95% confidence interval is 0.00118. There are 0 homozygotes in gnomad4. There are 16 alleles in male gnomad4 subpopulation. Median coverage is 23. This position pass quality control queck.
BS2
High Hemizygotes in GnomAd4 at 16 XL gene
