Variant summary

Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BP4_StrongBP6BS1BS2_Supporting

The NM_001195263.2(PDZD7):c.2357G>A(p.Arg786Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000197 in 1,516,090 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. 10/14 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R786W) has been classified as Uncertain significance.

Genes affected

PDZD7 (HGNC:26257): (PDZ domain containing 7) This gene encodes a ciliary protein homologous to proteins which are mutated in Usher syndrome patients, and mutations and translocations involving this gene have been associated with two types of Usher syndrome. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.008478075).

BP6

Variant 10-101010532-C-T is Benign according to our data. Variant chr10-101010532-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 178524.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000982 (136/138444) while in subpopulation AFR AF = 0.00296 (121/40822). AF 95% confidence interval is 0.00253. There are 0 homozygotes in GnomAd4. There are 67 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR,Unknown geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
