Disease or Syndrome
Synonyms: Benign symmetrical lipomatosis; Launois-Bensaude syndrome; Lipodystrophy, cephalothoracic; Lipomatosis familial benign cervical; Madelung disease; Madelung's disease
SNOMED CT: Multiple symmetrical lipomatosis (238902007); LMS - Multiple symmetrical lipomatosis (238902007); Launois Bensaude lipomatosis (238902007); Madelung disease (238902007); Madelung neck (238902007)
Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
141025
Concept ID:
C0441748
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).
Autosomal dominant inheritance
MedGen UID:
141047
Concept ID:
C0443147
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.
Mitochondrial inheritance
MedGen UID:
165802
Concept ID:
C0887941
Genetic Function
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on the mitochondrial genome. Because the mitochondrial genome is essentially always maternally inherited, a mitochondrial condition can only be transmitted by females, although the condition can affect both sexes. The proportion of mutant mitochondria can vary (heteroplasmy).

Definition

Multiple symmetric lipomatosis (MSL) is an autosomal recessive metabolic disorder characterized by the growth of unencapsulated masses of adipose tissue with predilection for the cervical and thoracic regions. The lipoma growth is striking and disfiguring, and growth around the neck may cause difficulty swallowing or breathing. The age at onset ranges from childhood to young adulthood. Most, but not all, patients develop axonal peripheral neuropathy, which can appear at any age and varies in severity. Laboratory studies in MSL show low leptin (164160), low adiponectin (605441), variably increased lactate, and increased FGF21 (609436). Some patients may have insulin resistance. The disorder is exclusively associated with a particular MFN2 mutation (R707W; 608507.0013), usually in the homozygous state, but sometimes in the compound heterozygous state (Rocha et al., 2017; Capel et al., 2018). [from OMIM]

Clinical features

From HPO
Multiple lipomas
MedGen UID:
677074
Concept ID:
C0745730
Finding
The presence of multiple lipomas (a type of benign tissue made of fatty tissue).
Clubfoot
MedGen UID:
3130
Concept ID:
C0009081
Congenital Abnormality
Clubfoot is a congenital limb deformity defined as fixation of the foot in cavus, adductus, varus, and equinus (i.e., inclined inwards, axially rotated outwards, and pointing downwards) with concomitant soft tissue abnormalities (Cardy et al., 2007). Clubfoot may occur in isolation or as part of a syndrome (e.g., diastrophic dysplasia, 222600). Clubfoot has been reported with deficiency of long bones and mirror-image polydactyly (Gurnett et al., 2008; Klopocki et al., 2012).
Hearing impairment
MedGen UID:
235586
Concept ID:
C1384666
Disease or Syndrome
A decreased magnitude of the sensory perception of sound.
Peripheral neuropathy
MedGen UID:
18386
Concept ID:
C0031117
Disease or Syndrome
Peripheral neuropathy is a general term for any disorder of the peripheral nervous system. The main clinical features used to classify peripheral neuropathy are distribution, type (mainly demyelinating versus mainly axonal), duration, and course.
Areflexia
MedGen UID:
115943
Concept ID:
C0234146
Finding
Absence of neurologic reflexes such as the knee-jerk reaction.
Peripheral axonal neuropathy
MedGen UID:
266071
Concept ID:
C1263857
Disease or Syndrome
An abnormality characterized by disruption of the normal functioning of peripheral axons.
Distal sensory impairment
MedGen UID:
335722
Concept ID:
C1847584
Finding
An abnormal reduction in sensation in the distal portions of the extremities.
Kyphosis
MedGen UID:
44042
Concept ID:
C0022821
Anatomical Abnormality
Exaggerated anterior convexity of the thoracic vertebral column.
Lipodystrophy
MedGen UID:
6111
Concept ID:
