Genes affected

TCTA (HGNC:11692): (T cell leukemia translocation altered) Involved in negative regulation of osteoclast differentiation and osteoclast fusion. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

TCTA links:

RHOA (HGNC:667): (ras homolog family member A) This gene encodes a member of the Rho family of small GTPases, which cycle between inactive GDP-bound and active GTP-bound states and function as molecular switches in signal transduction cascades. Rho proteins promote reorganization of the actin cytoskeleton and regulate cell shape, attachment, and motility. Overexpression of this gene is associated with tumor cell proliferation and metastasis. Multiple alternatively spliced variants have been identified. [provided by RefSeq, Sep 2015]

Ambry Genetics

Nov 15, 2023

The c.207C>A (p.H69Q) alteration is located in exon 1 (coding exon 1) of the TCTA gene. This alteration results from a C to A substitution at nucleotide position 207, causing the histidine (H) at amino acid position 69 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
