Genes affected

HMBOX1 (HGNC:26137): (homeobox containing 1) Enables double-stranded telomeric DNA binding activity; identical protein binding activity; and sequence-specific double-stranded DNA binding activity. Involved in negative regulation of transcription by RNA polymerase II; positive regulation of telomerase activity; and positive regulation of telomere maintenance via telomerase. Located in several cellular components, including centrosome; chromosome, telomeric region; and nuclear body. [provided by Alliance of Genome Resources, Apr 2022]

The c.914A>G (p.N305S) alteration is located in exon 8 (coding exon 6) of the HMBOX1 gene. This alteration results from a A to G substitution at nucleotide position 914, causing the asparagine (N) at amino acid position 305 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
