Genes affected

SCYL1 (HGNC:14372): (SCY1 like pseudokinase 1) This gene encodes a transcriptional regulator belonging to the SCY1-like family of kinase-like proteins. The protein has a divergent N-terminal kinase domain that is thought to be catalytically inactive, and can bind specific DNA sequences through its C-terminal domain. It activates transcription of the telomerase reverse transcriptase and DNA polymerase beta genes. The protein has been localized to the nucleus, and also to the cytoplasm and centrosomes during mitosis. Multiple transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.011386067).
• BP6: Variant 11-65526041-G-A is Benign according to our data. Variant chr11-65526041-G-A is described in ClinVar as [Benign]. Clinvar id is 727353.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00527 (802/152300) while in subpopulation AFR AF= 0.0178 (738/41556). AF 95% confidence interval is 0.0167. There are 8 homozygotes in gnomad4. There are 360 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 8 AR gene
