Genes affected

H19 (HGNC:4713): (H19 imprinted maternally expressed transcript) This gene is located in an imprinted region of chromosome 11 near the insulin-like growth factor 2 (IGF2) gene. This gene is only expressed from the maternally-inherited chromosome, whereas IGF2 is only expressed from the paternally-inherited chromosome. The product of this gene is a long non-coding RNA which functions as a tumor suppressor. Mutations in this gene have been associated with Beckwith-Wiedemann Syndrome and Wilms tumorigenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

MRPL23 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.
