This inadvertent countertransference can give rise to inappropriate clinical responses, including excessive use of medication, inappropriate mothering, and punitive use of limit setting and interpretation.Some clients feel the diagnosis is helpful, allowing them to understand that they are not alone and to connect with others with BPD who have developed helpful coping mechanisms. However, others experience the term "borderline personality disorder" as a pejorative label rather than an informative diagnosis. They report concerns that their self-destructive behavior is incorrectly perceived as manipulative and that the stigma surrounding this disorder limits their access to health care. Indeed, mental health professionals frequently refuse to provide services to those who have received a BPD diagnosis. Terminology
Because of concerns around stigma, and because of a move away from the original theoretical basis for the term (see history), there is ongoing debate about renaming borderline personality disorder. While some clinicians agree with the current name, others argue that it should be changed, since many who are labelled with borderline personality disorder find the name unhelpful, stigmatizing, or inaccurate. Valerie Porr, president of Treatment and Research Advancement Association for Personality Disorders states that "the name BPD is confusing, imparts no relevant or descriptive information, and reinforces existing stigma".Alternative suggestions for names include emotional regulation disorder or emotional dysregulation disorder. Impulse disorder and interpersonal regulatory disorder are other valid alternatives, according to John G. Gunderson of McLean Hospital in the United States.

Causes
Mutations in gene encoding filamin B
Filamins are cytoplasmic proteins that regulate the structure and activity of the cytoskeleton. These proteins serve as scaffolds on which intracellular signaling and protein trafficking are organized. Filamin B has been found to be expressed in human growth plate chondrocytes, which are especially important in vertebrae segmentation and skeleton morphogenesis. Genetic analysis of patients with Larsen syndrome has found the syndrome is caused by missense mutations in the gene that codes for filamin B. These mutations cause an accelerated rate of apoptosis in the epiphyseal growth plates of individuals with the mutation. The defects can cause short stature and other symptoms associated with Larsen syndrome. Localization
Genetic analysis has found that a gene linked to Larsen syndrome, LAR1, is strongly linked to chromosome 3p markers. The locus of this gene is found in a region defined distally by D3S1581 and proximally by D3S1600. This location can be mapped to chromosome region 3p21.1-14.1. Human type VII collagen gene is found within this region in chromosome region 3p21.1. It is reasonable to believe that the joint abnormalities and cardiac anomalies associated with Larsen syndrome are related to the fact that the human type VII collagen gene is found within the same chromosome region as the LAR1 gene.
