Genes affected
OLA1 (HGNC:28833): (Obg like ATPase 1) This gene encodes a member of the GTPase protein family. The encoded protein interacts with breast cancer-associated gene 1 (BRCA1) and BRCA1-associated RING domain protein (BARD1), and is involved in centrosome regulation. Overexpression of this gene has been observed in multiple types of cancer and may be associated with poor survival. Pseudogenes of this gene have been defined on chromosomes 17 and 22.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2022The c.434T>C (p.I145T) alteration is located in exon 5 (coding exon 4) of the OLA1 gene. This alteration results from a T to C substitution at nucleotide position 434, causing the isoleucine (I) at amino acid position 145 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
