Genes affected
PQBP1 (HGNC:9330): (polyglutamine binding protein 1) This gene encodes a nuclear polyglutamine-binding protein that is involved with transcription activation. The encoded protein contains a WW domain. Mutations in this gene have been found in patients with Renpenning syndrome 1 and other syndromes with X-linked cognitive disability. Multiple alternatively spliced transcript variants that encode different protein isoforms have been described for this gene.[provided by RefSeq, Nov 2009]
SLC35A2 (HGNC:11022): (solute carrier family 35 member A2) This gene encodes a member of the nucleotide-sugar transporter family. The encoded protein is a multi-pass membrane protein. It transports UDP-galactose from the cytosol into Golgi vesicles, where it serves as a glycosyl donor for the generation of glycans. Mutations in this gene cause congenital disorder of glycosylation type IIm (CDG2M). Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.81).
BP6
Variant X-48903090-C-T is Benign according to our data. Variant chrX-48903090-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 95308.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000651 (73/112214) while in subpopulation NFE AF = 0.00111 (59/53189). AF 95% confidence interval is 0.000882. There are 0 homozygotes in GnomAd4. There are 27 alleles in the male GnomAd4 subpopulation. Median coverage is 22. This position passed quality control check.
BS2
High Hemizygotes in GnomAd4 at 27 XL gene
