Genes affected

BSX (HGNC:20450): (brain specific homeobox) 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 eating behavior; mammary gland involution; and positive regulation of transcription by RNA polymerase II. Predicted to be located in cytoplasm. Predicted to be part of chromatin. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Nov 22, 2022

The c.611T>C (p.L204P) alteration is located in exon 3 (coding exon 3) of the BSX gene. This alteration results from a T to C substitution at nucleotide position 611, causing the leucine (L) at amino acid position 204 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
