Genes affected

ABRAXAS2 (HGNC:28975): (abraxas 2, BRISC complex subunit) Enables microtubule binding activity and polyubiquitin modification-dependent protein binding activity. Involved in several processes, including mitotic spindle assembly; protein K63-linked deubiquitination; and response to ischemia. Located in cytoplasm. Part of BRISC complex. Colocalizes with microtubule minus-end; midbody; and spindle pole centrosome. [provided by Alliance of Genome Resources, Apr 2022]

Jun 06, 2023

The c.656A>C (p.K219T) alteration is located in exon 7 (coding exon 7) of the FAM175B gene. This alteration results from a A to C substitution at nucleotide position 656, causing the lysine (K) at amino acid position 219 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
