Genes affected

MAP1S (HGNC:15715): (microtubule associated protein 1S) Enables DNA binding activity and cytoskeletal protein binding activity. Involved in microtubule bundle formation; neuron projection morphogenesis; and regulation of chromatin disassembly. Located in several cellular components, including microtubule cytoskeleton; nuclear lumen; and perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.877C>T (p.P293S) alteration is located in exon 5 (coding exon 5) of the MAP1S gene. This alteration results from a C to T substitution at nucleotide position 877, causing the proline (P) at amino acid position 293 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
