Genes affected

MYADM (HGNC:7544): (myeloid associated differentiation marker) Involved in several processes, including negative regulation of heterotypic cell-cell adhesion; negative regulation of macromolecule metabolic process; and negative regulation of protein kinase C signaling. Located in several cellular components, including cortical actin cytoskeleton; membrane raft; and ruffle. [provided by Alliance of Genome Resources, Apr 2022]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.890C>T (p.A297V) alteration is located in exon 2 (coding exon 1) of the MYADM gene. This alteration results from a C to T substitution at nucleotide position 890, causing the alanine (A) at amino acid position 297 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
