Genes affected

MAK16 (HGNC:13703): (MAK16 homolog) Enables RNA binding activity. Predicted to be involved in maturation of 5.8S rRNA and maturation of LSU-rRNA. Located in nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

MAK16 links:

TTI2 (HGNC:26262): (TELO2 interacting protein 2) This gene encodes a regulator of the DNA damage response. The protein is a component of the Triple T complex (TTT) which also includes telomere length regulation protein and TELO2 interacting protein 1. The TTT complex is involved in cellular resistance to DNA damage stresses and may act as a regulator of phosphoinositide-3-kinase-related protein kinase (PIKK) abundance.

Feb 02, 2024

The c.758C>T (p.S253F) alteration is located in exon 10 (coding exon 10) of the MAK16 gene. This alteration results from a C to T substitution at nucleotide position 758, causing the serine (S) at amino acid position 253 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
