Genes affected

NAA10 (HGNC:18704): (N-alpha-acetyltransferase 10, NatA catalytic subunit) N-alpha-acetylation is among the most common post-translational protein modifications in eukaryotic cells. This process involves the transfer of an acetyl group from acetyl-coenzyme A to the alpha-amino group on a nascent polypeptide and is essential for normal cell function. This gene encodes an N-terminal acetyltransferase that functions as the catalytic subunit of the major amino-terminal acetyltransferase A complex. Mutations in this gene are the cause of Ogden syndrome. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jan 2012]

NAA10 links:

ARHGAP4 (HGNC:674): (Rho GTPase activating protein 4) This gene encodes a member of the rhoGAP family of proteins which play a role in the regulation of small GTP-binding proteins belonging to the RAS superfamily. The protein encoded by the orthologous gene in rat is localized to the Golgi complex and can redistribute to microtubules. The rat protein stimulates the activity of some Rho GTPases in vitro. Genomic deletions of this gene and a neighboring gene have been found in patients with nephrogenic diabetes insipidus. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

Computational evidence support a benign effect (BayesDel_noAF=-0.39).

BP6

Variant X-153933981-G-A is Benign according to our data. Variant chrX-153933981-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 435923.

BP7

Synonymous conserved (PhyloP=0.312 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0000808 (9/111323) while in subpopulation AFR AF = 0.000229 (7/30530). AF 95% confidence interval is 0.000107. There are 0 homozygotes in GnomAd4. There are 0 alleles in the male GnomAd4 subpopulation. Median coverage is 23. This position passed quality control check.
