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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.1033G>A (p.A345T) alteration is located in exon 5 (coding exon 5) of the MAP1S gene. This alteration results from a G to A substitution at nucleotide position 1033, causing the alanine (A) at amino acid position 345 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
