Genes affected

BBS9 (HGNC:30000): (Bardet-Biedl syndrome 9) This gene is downregulated by parathyroid hormone in osteoblastic cells, and therefore is thought to be involved in parathyroid hormone action in bones. The exact function of this gene has not yet been determined. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jan 2017]

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (MetaRNN=0.0043776035).

BP6

Variant 7-33383725-A-C is Benign according to our data. Variant chr7-33383725-A-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 263122.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 = 0.0117 (1781/152318) while in subpopulation AFR AF = 0.0405 (1681/41556). AF 95% confidence interval is 0.0388. There are 37 homozygotes in GnomAd4. There are 838 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
