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 Gene-Disease associations (from GenCC):

• non-acquired combined pituitary hormone deficiency with spine abnormalities

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: G2P, Orphanet, Labcorp Genetics (formerly Invitae)
• hypothyroidism due to deficient transcription factors involved in pituitary development or function

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 9-136197833-G-A is Benign according to our data. Variant chr9-136197833-G-A is described in ClinVar as Benign. ClinVar VariationId is 1185281.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.575 is higher than 0.05.
