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.17G>T (p.G6V) alteration is located in exon 1 (coding exon 1) of the MAP1S gene. This alteration results from a G to T substitution at nucleotide position 17, causing the glycine (G) at amino acid position 6 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
