Description

One of multiple examples of independent probands with variants precluding the stable formation of the most potent FGF8 isoforms (b and f). Multiple bioinformatic algorithms agree that this variant would affect splicing.

Description

Compatible clinical presentation with ACMG criteria:PVS1;PM2;PP3;PP6.
