Frontometaphyseal dysplasia (FMD) belongs to a group of overlapping skeletal dysplasias, the common molecular basis of which are mutations of FLNA, the gene encoding filamin A.
A dual phenotype of periventricular nodular heterotopia and frontometaphyseal dysplasia in one patient caused by a single FLNA mutation leading to two functionally different aberrant transcripts.
Missense mutations of the FLNA gene, which encodes for the protein filamin A, have recently been shown to cause OPD2 and the allelic syndromes otopalatodigital type 1, Melnick-Needles, and frontometaphyseal dysplasia.
Phenotypic series of frontometaphyseal dysplasia also comprise variants in FLNA (type 1) and two patients with a heterozygous variant in TAB2 (type 3).
High phenotypic diversity, ranging from PH to otopalatodigital syndrome and frontometaphyseal dysplasia has been described in association with FLNA mutations.
Phenotypic series of frontometaphyseal dysplasia also comprise variants in FLNA (type 1) and two patients with a heterozygous variant in TAB2 (type 3).
We identified localized mutations in FLNA that conserve the reading frame and lead to a broad range of congenital malformations, affecting craniofacial structures, skeleton, brain, viscera and urogenital tract, in four X-linked human disorders: otopalatodigital syndrome types 1 (OPD1; OMIM 311300) and 2 (OPD2; OMIM 304120), frontometaphyseal dysplasia (FMD; OMIM 305620) and Melnick-Needles syndrome (MNS; OMIM 309350).

OPD1 belongs to a group of X-linked skeletal dysplasias known as oto-palato-digital syndrome spectrum disorders that also include OPD2, Melnick-Needles syndrome (MNS), and frontometaphyseal dysplasia (FMD).
