Genes affected

HBP1 (HGNC:23200): (HMG-box transcription factor 1) Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in negative regulation of lipid transport; negative regulation of reactive oxygen species biosynthetic process; and negative regulation of transcription by RNA polymerase II. Located in nuclear speck. Biomarker of osteoarthritis. [provided by Alliance of Genome Resources, Apr 2022]

The c.1145C>T (p.S382F) alteration is located in exon 9 (coding exon 8) of the HBP1 gene. This alteration results from a C to T substitution at nucleotide position 1145, causing the serine (S) at amino acid position 382 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
