Hypotonia-failure to thrive-microcephaly syndrome

MedGen UID:
481292
•Concept ID:
C3279662
•
Disease or Syndrome
Synonyms: Leukotriene c4 synthase deficiency; LTC4 SYNTHASE DEFICIENCY
SNOMED CT: Deficiency of leukotriene C4 synthase (717185008); Leukotriene C4 synthase deficiency (717185008); Hypotonia with failure to thrive and microcephaly syndrome (717185008)
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 recessive inheritance (Orphanet)
 
Gene (location): LTC4S (5q35.3)
 
Monarch Initiative: MONDO:0013539
OMIM®: 614037
Orphanet: ORPHA79507

Definition

An extremely rare fatal neurometabolic developmental disorder with clinical characteristics of muscular hypotonia, psychomotor retardation, failure to thrive, and microcephaly. [from SNOMEDCT_US]

Clinical features

From HPO
Failure to thrive in infancy
MedGen UID:

Global developmental delay
MedGen UID:
107838
•Concept ID:
C0557874
•
Finding
A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age.

Hypotonia
MedGen UID:
10133
•Concept ID:
C0026827
•
Finding
Hypotonia is an abnormally low muscle tone (the amount of tension or resistance to movement in a muscle). Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist.

Microcephaly
MedGen UID:
1644158
•Concept ID:
C4551563
•
Finding
Head circumference below 2 standard deviations below the mean for age and gender.

Reduced circulating leukotriene C4 concentration
MedGen UID:
1684684
•Concept ID:
C5139109
•
Finding
An abnormally decreased concentration of leukotriene C4 in the blood circulation.
