Genes affected
FOXN1 (HGNC:12765): (forkhead box N1) Mutations in the winged-helix transcription factor gene at the nude locus in mice and rats produce the pleiotropic phenotype of hairlessness and athymia, resulting in a severely compromised immune system. This gene is orthologous to the mouse and rat genes and encodes a similar DNA-binding transcription factor that is thought to regulate keratin gene expression. A mutation in this gene has been correlated with T-cell immunodeficiency, the skin disorder congenital alopecia, and nail dystrophy. Alternative splicing in the 5' UTR of this gene has been observed.

RSKR (HGNC:26314): (ribosomal protein S6 kinase related) Predicted to enable protein kinase activity. Predicted to be involved in protein phosphorylation. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

BS1
Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.00397 (573/144290) while in subpopulation EAS AF= 0.0132 (63/4762). AF 95% confidence interval is 0.0106. There are 8 homozygotes in gnomad4. There are 274 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 8 SD gene
