Genes affected
PDE6D (HGNC:8788): (phosphodiesterase 6D) This gene encodes the delta subunit of rod-specific photoreceptor phosphodiesterase (PDE), a key enzyme in the phototransduction cascade. A similar protein in cow functions in solubilizing membrane-bound PDE. In addition to its role in the PDE complex, the encoded protein is thought to bind to prenyl groups of proteins to target them to subcellular organelles called cilia. Mutations in this gene are associated with Joubert syndrome-22. Alternative splicing results in multiple splice variants. [provided by RefSeq, Mar 2014]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -18 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.46).
BP6
Variant 2-231737179-T-G is Benign according to our data. Variant chr2-231737179-T-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 446086.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 = 0.00337 (514/152298) while in subpopulation AFR AF = 0.0117 (484/41542). AF 95% confidence interval is 0.0108. There are 1 homozygotes in GnomAd4. There are 247 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 9 AR gene
