Genes affected

LHB (HGNC:6584): (luteinizing hormone subunit beta) This gene is a member of the glycoprotein hormone beta chain family and encodes the beta subunit of luteinizing hormone (LH). Glycoprotein hormones are heterodimers consisting of a common alpha subunit and an unique beta subunit which confers biological specificity. LH is expressed in the pituitary gland and promotes spermatogenesis and ovulation by stimulating the testes and ovaries to synthesize steroids. The genes for the beta chains of chorionic gonadotropin and for luteinizing hormone are contiguous on chromosome 19q13.3. Mutations in this gene are associated with hypogonadism which is characterized by infertility and pseudohermaphroditism. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jul 26, 2021

The c.211C>G (p.P71A) alteration is located in exon 3 (coding exon 3) of the LHB gene. This alteration results from a C to G substitution at nucleotide position 211, causing the proline (P) at amino acid position 71 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
