Genes affected

EIF1AX (HGNC:3250): (eukaryotic translation initiation factor 1A X-linked) This gene encodes an essential eukaryotic translation initiation factor. The protein is required for the binding of the 43S complex (a 40S subunit, eIF2/GTP/Met-tRNAi and eIF3) to the 5' end of capped RNA. [provided by RefSeq, Jul 2008]

ENSG00000201882 (HGNC:):

SCARNA9L (HGNC:33559): (small Cajal body-specific RNA 9 like)

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant X-20135846-C-T is Benign according to our data. Variant chrX-20135846-C-T is described in ClinVar as Benign. ClinVar VariationId is 787515.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00934 (1044/111820) while in subpopulation AFR AF = 0.0317 (976/30759). AF 95% confidence interval is 0.0301. There are 13 homozygotes in GnomAd4. There are 289 alleles in the male GnomAd4 subpopulation. Median coverage is 23. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 13 gene
