Genes affected

LHX3 (HGNC:6595): (LIM homeobox 3) This gene encodes a member of a large family of proteins which carry the LIM domain, a unique cysteine-rich zinc-binding domain. The encoded protein is a transcription factor that is required for pituitary development and motor neuron specification. Mutations in this gene cause combined pituitary hormone deficiency 3. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

LHX3 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 7 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 9-136200736-CA-C is Pathogenic according to our data. Variant chr9-136200736-CA-C is described in ClinVar as [Pathogenic]. Clinvar id is 9023.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr9-136200736-CA-C is described in Lovd as [Pathogenic].
