Genes affected

FANK1 (HGNC:23527): (fibronectin type III and ankyrin repeat domains 1) Involved in regulation of apoptotic process and regulation of transcription, DNA-templated. Located in cytosol and nucleoplasm. Colocalizes with chromatin. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.00315395).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0235 (3575/152154) while in subpopulation NFE AF= 0.0331 (2247/67968). AF 95% confidence interval is 0.0319. There are 79 homozygotes in gnomad4. There are 1684 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 79 AR gene
