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.

The c.313G>A (p.A105T) alteration is located in exon 3 (coding exon 3) of the SCYL1 gene. This alteration results from a G to A substitution at nucleotide position 313, causing the alanine (A) at amino acid position 105 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
