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]
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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.743A>G (p.Q248R) alteration is located in exon 10 (coding exon 10) of the MAK16 gene. This alteration results from a A to G substitution at nucleotide position 743, causing the glutamine (Q) at amino acid position 248 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
