Genes affected

SIX6 (HGNC:10892): (SIX homeobox 6) The protein encoded by this gene is a homeobox protein that is similar to the Drosophila 'sine oculis' gene product. This gene is found in a cluster of related genes on chromosome 14 and is thought to be involved in eye development. Defects in this gene are a cause of isolated microphthalmia with cataract type 2 (MCOPCT2). [provided by RefSeq, Jul 2008]

C14orf39 (HGNC:19849): (chromosome 14 open reading frame 39) Predicted to be involved in gamete generation and meiosis I. Predicted to be located in chromosome. Predicted to be active in central element. Implicated in primary ovarian insufficiency 18 and spermatogenic failure 52. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0000394 (6/152184) while in subpopulation NFE AF = 0.0000882 (6/68030). AF 95% confidence interval is 0.0000376. There are 0 homozygotes in GnomAd4. There are 2 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
