Genes affected

ZWILCH (HGNC:25468): (zwilch kinetochore protein) Involved in protein localization to kinetochore. Located in kinetochore. Part of RZZ complex. [provided by Alliance of Genome Resources, Apr 2022]

ZWILCH links:

RPL4 (HGNC:10353): (ribosomal protein L4) Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 60S subunit. The protein belongs to the L4E family of ribosomal proteins. It is located in the cytoplasm. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Jul 2008]

Ambry Genetics

May 05, 2023

The c.34T>A (p.F12I) alteration is located in exon 1 (coding exon 1) of the ZWILCH gene. This alteration results from a T to A substitution at nucleotide position 34, causing the phenylalanine (F) at amino acid position 12 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
