Summaries for Frontometaphyseal Dysplasia 1

OMIM : 54
Frontometaphyseal dysplasia-1 is 1 of 4 otopalatodigital syndromes caused by mutations in the FLNA gene. The disorders, which include otopalatodigital syndrome-1 (OPD1; 311300), otopalatodigital syndrome-2 (OPD2; 304120), and Melnick-Needles syndrome (MNS; 309350), constitute a phenotypic spectrum. At the mild end of the spectrum, males with OPD1 have cleft palate and mild skeletal anomalies with conductive deafness caused by ossicular anomalies. FMD1 is characterized by a generalized skeletal dysplasia, deafness, and urogenital defects. Males with OPD2 have disabling skeletal anomalies in addition to variable malformations in the hindbrain, heart, intestines, and kidneys that frequently lead to perinatal death. The most severe phenotype, MNS, is characterized by a skeletal dysplasia in the heterozygote. Affected males exhibit severe malformations similar to those observed in individuals with OPD2, resulting in prenatal lethality or death in the first few months of life (review by Robertson, 2005). Verloes et al. (2000) suggested that these disorders constitute a single entity, which they termed 'frontootopalatodigital osteodysplasia.' (305620)

MalaCards based summary : Frontometaphyseal Dysplasia 1, also known as fmd1, is related to fibromuscular dysplasia and frontometaphyseal dysplasia, and has symptoms including scoliosis, hirsutism and coarse facial features. An important gene associated with Frontometaphyseal Dysplasia 1 is FLNA (Filamin A). Affiliated tissues include heart, kidney and bone.
