Disease or Syndrome
Synonyms: Intermediate congenital nemaline myopathy; Intermediate congenital NM; intermediate nemaline myopathy
SNOMED CT: Intermediate nemaline myopathy (1197156008)
Modes of inheritance:
Autosomal recessive inheritance

•
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

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.

Definition

A type of nemaline myopathy that shows features of typical nemaline myopathy in neonates with a more severe progression. Neonates present with spontaneous anti-gravity movements and active respiratory muscles, but with a progressive generalized weakness which prevents achievement of gross motor milestones or leads to loss of ambulation and/or independent respiration by age 11 years. Children often develop joint contractures. The ACTA1 (1q42.13), NEB (2q22) or TPM3 (1q21.2) genes have been associated with this disease. The transmission pattern of the disease is autosomal recessive or dominant. [from SNOMEDCT_US]
