Genes affected
OPHN1 (HGNC:8148): (oligophrenin 1) This gene encodes a Rho-GTPase-activating protein that promotes GTP hydrolysis of Rho subfamily members. Rho proteins are important mediators of intracellular signal transduction, which affects cell migration and cell morphogenesis. Mutations in this gene are responsible for OPHN1-related X-linked cognitive disability with cerebellar hypoplasia and distinctive facial dysmorhphism. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

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

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.51).
BP6
Variant X-68073156-G-A is Benign according to our data. Variant chrX-68073156-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 211793.
BP7
Synonymous conserved (PhyloP=0.519 with no splicing effect.
BS1
Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000915 (100/1093058) while in subpopulation EAS AF = 0.000133 (4/30102). AF 95% confidence interval is 0.0000458. There are 0 homozygotes in GnomAdExome4. There are 35 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check.
BS2
High Hemizygotes in GnomAdExome4 at 35 XL gene
