Summaries for Leopard Syndrome 1

OMIM : 57 LEOPARD is an acronym for the manifestations of this syndrome as listed by Gorlin et al. (1969): multiple lentigines, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonic stenosis, abnormal genitalia, retardation of growth, and sensorineural deafness. (151100)

MalaCards based summary : Leopard Syndrome 1, also known as multiple lentigines, is related to leopard syndrome and noonan syndrome with multiple lentigines, and has symptoms including hyposmia An important gene associated with Leopard Syndrome 1 is PTPN11 (Protein Tyrosine Phosphatase, Non-Receptor Type 11). Affiliated tissues include ovary and heart, and related phenotypes are hypertelorism and low-set ears
