Variant summary

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

The NM_001367624.2(ZNF469):c.2407G>T(p.Ala803Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00235 in 1,550,118 control chromosomes in the GnomAD database, including 68 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/19 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. A803T) has been classified as Uncertain significance.

Genes affected

ZNF469 (HGNC:23216): (zinc finger protein 469) This gene encodes a zinc-finger protein. Low-percent homology to certain collagens suggests that it may function as a transcription factor or extra-nuclear regulator factor for the synthesis or organization of collagen fibers. Mutations in this gene cause brittle cornea syndrome. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (MetaRNN=0.0019454062).

BP6

Variant 16-88429877-G-T is Benign according to our data. Variant chr16-88429877-G-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 320886.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 (1782/152300) while in subpopulation AFR AF = 0.0397 (1649/41552). AF 95% confidence interval is 0.0381. There are 35 homozygotes in GnomAd4. There are 853 alleles in the male GnomAd4 subpopulation. Median coverage is 34. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 35 AR,AD gene
