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]

TIMM17B (HGNC:17310): (translocase of inner mitochondrial membrane 17B) This gene encodes a multipass transmembrane protein that forms an integral component of the mitochondrial translocase TIM23 complex. This complex facilitates the transport of mitochondrial proteins from the cytosol across the mitochondrial inner membrane and into the mitochondrion. There is a pseudogene for this gene on chromosome 12. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BP6: Variant X-48897951-A-G is Benign according to our data. Variant chrX-48897951-A-G is described in ClinVar as Likely_benign. ClinVar VariationId is 1203191.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00138 (154/111949) while in subpopulation NFE AF = 0.000848 (45/53045). AF 95% confidence interval is 0.000651. There are 1 homozygotes in GnomAd4. There are 70 alleles in the male GnomAd4 subpopulation. Median coverage is 24. This position passed quality control check.
• BS2: High Hemizygotes in GnomAd4 at 70 XL gene
