The c.53C>T (p.P18L) alteration is located in exon 4 (coding exon 1) of the MAP2 gene. This alteration results from a C to T substitution at nucleotide position 53, causing the proline (P) at amino acid position 18 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.

HelpRecord last updated May 08, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
