Genes affected

MZT2B (HGNC:25886): (mitotic spindle organizing protein 2B) Located in cytosol; microtubule cytoskeleton; and nucleoplasm. Part of gamma-tubulin large complex. [provided by Alliance of Genome Resources, Apr 2022]

MZT2B links:

SMPD4 (HGNC:32949): (sphingomyelin phosphodiesterase 4) The protein encoded by this gene is a sphingomyelinase that catalyzes the hydrolysis of membrane sphingomyelin to form phosphorylcholine and ceramide. This gene is activated by DNA damage, cellular stress, and tumor necrosis factor, but it is downregulated by wild-type p53. The encoded protein localizes to the endoplasmic reticulum and Golgi network. [provided by RefSeq, Mar 2017]

The c.308C>T (p.P103L) alteration is located in exon 2 (coding exon 2) of the MZT2B gene. This alteration results from a C to T substitution at nucleotide position 308, causing the proline (P) at amino acid position 103 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
