Genes affected

PAX6 (HGNC:8620): (paired box 6) This gene encodes paired box protein Pax-6, one of many human homologs of the Drosophila melanogaster gene prd. In addition to a conserved paired box domain, a hallmark feature of this gene family, the encoded protein also contains a homeobox domain. Both domains are known to bind DNA and function as regulators of gene transcription. Activity of this protein is key in the development of neural tissues, particularly the eye. This gene is regulated by multiple enhancers located up to hundreds of kilobases distant from this locus. Mutations in this gene or in the enhancer regions can cause ocular disorders such as aniridia and Peter's anomaly. Use of alternate promoters and alternative splicing results in multiple transcript variants encoding different isoforms. Interestingly, inclusion of a particular alternate coding exon has been shown to increase the length of the paired box domain and alter its DNA binding specificity. Consequently, isoforms that carry the shorter paired box domain regulate a different set of genes compared to the isoforms carrying the longer paired box domain. [provided by RefSeq, Mar 2019]

ACMG classification

Verdict is Benign. Variant got -18 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.43).
• BP6: Variant 11-31801591-C-T is Benign according to our data. Variant chr11-31801591-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 304359.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-31801591-C-T is described in Lovd as [Benign]. Variant chr11-31801591-C-T is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0106 (1618/152268) while in subpopulation AFR AF= 0.0377 (1567/41544). AF 95% confidence interval is 0.0362. There are 29 homozygotes in gnomad4. There are 780 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
