Genes affected
ATAT1 (HGNC:21186): (alpha tubulin acetyltransferase 1) This gene encodes a protein that localizes to clathrin-coated pits, where it acetylates alpha tubulin on lysine 40. This process may be important in microtubule growth, for instance during chemotaxis and the formation of cilium. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.769C>T (p.R257C) alteration is located in exon 10 (coding exon 10) of the ATAT1 gene. This alteration results from a C to T substitution at nucleotide position 769, causing the arginine (R) at amino acid position 257 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
