Genes affected

LHX4 (HGNC:21734): (LIM homeobox 4) This gene encodes a member of a large protein family which contains the LIM domain, a unique cysteine-rich zinc-binding domain. The encoded protein is a transcription factor involved in the control of differentiation and development of the pituitary gland. Mutations in this gene cause combined pituitary hormone deficiency 4. [provided by RefSeq, Dec 2010]

• short stature-pituitary and cerebellar defects-small sella turcica syndrome

  Inheritance: AD Classification: DEFINITIVE, STRONG, MODERATE, SUPPORTIVE Submitted by: Orphanet, Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae)
• combined pituitary hormone deficiencies, genetic form

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
• hypothyroidism due to deficient transcription factors involved in pituitary development or function

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.586 is higher than 0.05.
