Genes affected

XACT (HGNC:45056): (X active specific transcript) This gene produces a spliced long non-coding RNA that is thought to play a role in the control of X-chromosome inactivation (XCI). This transcript has been shown to specifically coat the active X chromosome in human pluripotent cells. [provided by RefSeq, Mar 2015]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
