not specified Uncertain:1
Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: Intronic in 2 transcripts. In other 2 transcripts, causes frameshift, but in the last exon.
