Description

Reported using an alternate transcript of the gene; Reported in a patient with developmental delay, seizures and high myopia (PMID: 29056246); Not observed at significant frequency in large population cohorts (gnomAD); Frameshift variant predicted to result in protein truncation as the last 51 amino acids are lost and replaced with 20 incorrect amino acids, although loss-of-function variants have not been reported downstream of this position in the protein; This variant is associated with the following publications: (PMID: 29056246)
