Genes affected

BARHL1 (HGNC:953): (BarH like homeobox 1) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including negative regulation of neuron apoptotic process; nervous system development; and sensory perception of sound. Predicted to be part of chromatin. Predicted to be active in nucleus. Biomarker of Alzheimer's disease; high grade glioma; and triple-receptor negative breast cancer.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.194G>A (p.R65Q) alteration is located in exon 1 (coding exon 1) of the BARHL1 gene. This alteration results from a G to A substitution at nucleotide position 194, causing the arginine (R) at amino acid position 65 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
