Genes affected

GDI1 (HGNC:4226): (GDP dissociation inhibitor 1) GDP dissociation inhibitors are proteins that regulate the GDP-GTP exchange reaction of members of the rab family, small GTP-binding proteins of the ras superfamily, that are involved in vesicular trafficking of molecules between cellular organelles. GDIs slow the rate of dissociation of GDP from rab proteins and release GDP from membrane-bound rabs. GDI1 is expressed primarily in neural and sensory tissues. Mutations in GDI1 have been linked to X-linked nonspecific cognitive disability. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

PP3

Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.

BP6

Variant X-154440483-C-T is Benign according to our data. Variant chrX-154440483-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 211077.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000241 (27/112115) while in subpopulation NFE AF = 0.000433 (23/53172). AF 95% confidence interval is 0.000295. There are 0 homozygotes in GnomAd4. There are 9 alleles in the male GnomAd4 subpopulation. Median coverage is 23. This position passed quality control check.

BS2

High Hemizygotes in GnomAd4 at 9 XL gene
