Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_001164688.2(RD3):c.584A>T(p.Asp195Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0101 in 1,596,836 control chromosomes in the GnomAD database, including 116 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D195Y) has been classified as Uncertain significance.

Genes affected

RD3 (HGNC:19689): (RD3 regulator of GUCY2D) This gene encodes a retinal protein that is associated with promyelocytic leukemia-gene product (PML) bodies in the nucleus. Mutations in this gene cause Leber congenital amaurosis type 12, a disease that results in retinal degeneration. Alternative splicing results in multiple transcript variants.

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (MetaRNN=0.005150646).

BP6

Variant 1-211479040-T-A is Benign according to our data. Variant chr1-211479040-T-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 445480.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0104 (1589/152316) while in subpopulation NFE AF = 0.0139 (942/68014). AF 95% confidence interval is 0.0131. There are 15 homozygotes in GnomAd4. There are 835 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 15 AR,AD gene
