Genes affected

PAX4 (HGNC:8618): (paired box 4) This gene is a member of the paired box (PAX) family of transcription factors. Members of this gene family typically contain a paired box domain, an octapeptide, and a paired-type homeodomain. These genes play critical roles during fetal development and cancer growth. The paired box 4 gene is involved in pancreatic islet development and mouse studies have demonstrated a role for this gene in differentiation of insulin-producing beta cells.

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00828 (772/93208) while in subpopulation AFR AF= 0.0312 (720/23084). AF 95% confidence interval is 0.0293. There are 7 homozygotes in gnomad4. There are 364 alleles in male gnomad4 subpopulation. Median coverage is 18. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
• BS2: High AC in GnomAd4 at 772 AD gene.
