Genes affected
MAP6D1 (HGNC:25753): (MAP6 domain containing 1) This gene encodes a protein highly similar to the mouse MAP6 domain containing 1 protein, which is related to the STOP proteins. Based on the study of the mouse protein, the encoded protein may function as a calmodulin-regulated neuronal protein that binds and stabilizes microtubules but also associates with the Golgi membranes through N-terminal palmitoylation.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.32G>T (p.C11F) alteration is located in exon 1 (coding exon 1) of the MAP6D1 gene. This alteration results from a G to T substitution at nucleotide position 32, causing the cysteine (C) at amino acid position 11 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
