Genes affected
MAST4 (HGNC:19037): (microtubule associated serine/threonine kinase family member 4) This gene encodes a member of the microtubule-associated serine/threonine protein kinases. The proteins in this family contain a domain that gives the kinase the ability to determine its own scaffold to control the effects of their kinase activities. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2014]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.743G>A (p.R248Q) alteration is located in exon 9 (coding exon 9) of the MAST4 gene. This alteration results from a G to A substitution at nucleotide position 743, causing the arginine (R) at amino acid position 248 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
