  IGHMBP2 gene mutations can present with two different phenotypes: 1) the severe SMARD1 (Spinal Muscular Atrophy associated with Respiratory Distress) or 2) the milder CMT2S. Both are rare and recessive in nature. [cmtausa.org]

• Hyporeflexia

  On examination, most patients with CMT exhibit distally dominant weakness, hyporeflexia, and muscle atrophy affecting the legs earlier and more significantly than the arms. [emedicine.medscape.com]

  Common clinical manifestations of CMTX1 disease, as in other forms of Charcot-Marie-Tooth (CMT) disease, are distal muscle wasting and weakness, hyporeflexia, distal sensory disturbance, and foot deformities. [pediatrics.aappublications.org]

  The proband's two younger sisters (II:3 and II:6) and niece (III:3) denied to have any neurological symptoms; however, neurological examinations uncovered mild atrophy, weakness in the intrinsic foot muscles (score 4 /5) and generalized hyporeflexia in [journals.plos.org]

• Areflexia

  Pain is rarely an initial symptom but most patients experience pain during the course of their disease. [ 6 ] Generalised tendon areflexia. There may be foot drop and foot deformity. [patient.info]

  In one study, ankle jerks were absent in 37.5%, and areflexia occurred in 12.5%. [emedicine.medscape.com]

  Physical examinations at age 5 revealed a mild atrophy and weakness of the intrinsic muscles of the feet (score 2/5), impaired dorsiflexion of the feet (score 2 3/5), generalized areflexia, and mildly diminished sensation of all modalities in regions [journals.plos.org]

Treatment for CMT There is no cure for CMT, but treatment can help manage some of the symptoms. [betterhealth.vic.gov.au]

We are beginning to explore such a genetic approach as a possible treatment for CMT2D, a dominant axonal neuropathy (type 2) caused by mutations in GARS. [jax.org]

Treatment and prognosis Unfortunately no effective drug for CMT exists. Treatment is largely supportive with rehabilitation therapy and surgery for skeletal deformities 5. [radiopaedia.org]

The wide range of disease severity and the overlapping of many signs can make pedigree construction and the determination of recurrence risks and prognosis challenging. The only recourse may be genotyping. [disorders.eyes.arizona.edu]
