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 GeneticsMay 23, 2024The c.428G>A (p.R143H) alteration is located in exon 6 (coding exon 6) of the MAK16 gene. This alteration results from a G to A substitution at nucleotide position 428, causing the arginine (R) at amino acid position 143 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
