Genes affected

DRC4 (HGNC:4166): (growth arrest specific 8) This gene includes 11 exons spanning 25 kb and maps to a region of chromosome 16 that is sometimes deleted in breast and prostrate cancer. The second intron contains an apparently intronless gene, C16orf3, that is transcribed in the opposite orientation. This gene is a putative tumor suppressor gene. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2013]

URAHP (HGNC:):

URAHP (HGNC:43695): (urate (hydroxyiso-) hydrolase, pseudogene) Predicted to enable hydroxyisourate hydrolase activity. Predicted to be involved in allantoin metabolic process; purine-containing compound catabolic process; and urate catabolic process. Predicted to be active in peroxisome.

ACMG classification

Our verdict: Benign. The variant received -11 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BP6: Variant 16-90042484-G-A is Benign according to our data. Variant chr16-90042484-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 475560.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-5.63 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.0000465 (68/1461448) while in subpopulation AFR AF = 0.000657 (22/33476). AF 95% confidence interval is 0.000444. There are 1 homozygotes in GnomAdExome4. There are 41 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
