Genes affected

KATNA1 (HGNC:6216): (katanin catalytic subunit A1) Microtubules, polymers of alpha and beta tubulin subunits, form the mitotic spindle of a dividing cell and help to organize membranous organelles during interphase. Katanin is a heterodimer that consists of a 60 kDa ATPase (p60 subunit A 1) and an 80 kDa accessory protein (p80 subunit B 1). The p60 subunit acts to sever and disassemble microtubules, while the p80 subunit targets the enzyme to the centrosome. This gene encodes the p80 subunit. This protein is a member of the AAA family of ATPases. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Feb 2011]

Nov 25, 2024

The c.458G>A (p.R153H) alteration is located in exon 4 (coding exon 3) of the KATNA1 gene. This alteration results from a G to A substitution at nucleotide position 458, causing the arginine (R) at amino acid position 153 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
