Genes affected

PCDH11X (HGNC:8656): (protocadherin 11 X-linked) This gene belongs to the protocadherin gene family, a subfamily of the cadherin superfamily. The encoded protein consists of an extracellular domain containing 7 cadherin repeats, a transmembrane domain and a cytoplasmic tail that differs from those of the classical cadherins. The gene is located in a major X/Y block of homology and its Y homolog, despite divergence leading to coding region changes, is the most closely related cadherin family member. The protein is thought to play a fundamental role in cell-cell recognition essential for the segmental development and function of the central nervous system. Disruption of this gene may be associated with developmental dyslexia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

ACMG classification

Our verdict: Benign. The variant received -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.55).
• BP6: Variant X-91835514-T-C is Benign according to our data. Variant chrX-91835514-T-C is described in ClinVar as Benign. ClinVar VariationId is 713259.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=3.06 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00564 (627/111211) while in subpopulation AFR AF = 0.0199 (607/30562). AF 95% confidence interval is 0.0186. There are 7 homozygotes in GnomAd4. There are 169 alleles in the male GnomAd4 subpopulation. Median coverage is 21. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 7 gene
