Generally, Phelan-McDermid syndrome will not be diagnosed prenatally. Testing usually is initiated as a result of trying to identify the cause of hypotonia or global developmental delay.

What is the ICd 10 code for deletion of chromosomes?

Other deletions of part of a chromosome 1 Q93.5 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail. 2 The 2021 edition of ICD-10-CM Q93.5 became effective on October 1, 2020. 3 This is the American ICD-10-CM version of Q93.5 - other international versions of ICD-10 Q93.5 may differ.

What are the disorders of the long arm of chromosome 15?

A genetic syndrome characterized by mental retardation, speech impairment, microcephaly, ataxia, and seizures. The majority of cases result from deletions on the long arm of chromosome 15.

What is the ICD code for chromosome replacement?

Q93.2 is a billable ICD code used to specify a diagnosis of chromosome replaced with ring, dicentric or isochromosome. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

What is PMS mutation?

The Developmental Synaptopathies Consortium defines PMS as being caused by SHANK3 mutations, a definition that excludes terminal deletions.

What is 22q13 deletion syndrome?

22q13 deletion syndrome (spoken as twenty-two q one three) is a genetic disorder caused by deletions or rearrangements on the q terminal end (long arm) of chromosome 22. Any abnormal genetic variation in the q13 region that presents with significant manifestations (phenotype) typical of a terminal deletion should be diagnosed as 22q13 deletion syndrome. 22q13 deletion syndrome is often placed in the more general category of Phelan-McDermid Syndrome (abbreviated PMS), which includes some mutations and microdeletions. The PMS name is less precise, since there is disagreement among researchers as to which variants belong in the PMS category. The Developmental Synaptopathies Consortium defines PMS as being caused by SHANK3 mutations, a definition that excludes terminal deletions. This latter definition of PMS is incompatible with the defintion of 22q13 deletion syndrome by those who first described 22q13 deletion syndrome.

What is billable code?

Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis. The Center for Medicare & Medicaid Services (CMS) requires medical coders to indicate whether or not a condition was present at the time of admission, in order to properly assign MS-DRG codes.

What is the Phelan-McDermid Syndrome Foundation?

The Phelan-McDermid Syndrome Foundation’s (PMSF) goal is to find effective clinical therapies and, eventually, a cure. In 2010, the PMSF launched a strategic plan for science to accelerate PMS research.

What is PMS in children?

As children grow, additional symptoms develop. People with PMS typically have moderate to severe developmental and intellectual impairment, most do not acquire functional language, and about 75% have been diagnosed with an autism spectrum disorder.

What test is done to determine if a child's deletion is de novo?

Parents should undergo metaphase FISH and/or karyotype testing to determine if the child’s deletion is de novo (spontaneous) or if it resulted from a parental chromosomal rearrangement, such as a balanced translocation or inversion, or if one of the parents themselves has the same deletion.

What is the genetic mutation of chromosome 22?

Phelan-McDermid syndrome (PMS) is a rare genetic condition caused by a deletion or other structural change of the terminal end of chromosome 22 in the 22 q13 region or a disease-causing mutation of the SHANK3 gene. Although the range and severity of symptoms may vary, PMS is generally thought to be characterized by neonatal hypotonia (low muscle tone in the newborn), normal growth, absent to severely delayed speech, moderate to profound developmental delay, and minor dysmorphic features.

Signs and symptoms

Affected individuals present with a broad array of medical and behavioral manifestations (tables 1 and 2). Patients are consistently characterized by global developmental delay, intellectual disability, speech abnormalities, ASD -like behaviors, hypotonia and mild dysmorphic features.

Cause

Various deletions affect the terminal region of the long arm of chromosome 22 (the paternal chromosome in 75% of cases ), from 22q13.3 to 22qter. Although the deletion is most typically a result of a de novo mutation, there is an inherited form resulting from familial chromosomal translocations involving the 22 chromosome.

Epidemiology

The true prevalence of PMS has not been determined. More than 1,200 people have been identified worldwide according to the Phelan–McDermid Syndrome Foundation. However, it is believed to be underdiagnosed due to inadequate genetic testing and lack of specific clinical features. It is known to occur with equal frequency in males and females.

History

The first case of PMS was described in 1985 by Watt et al., who described a 14-year-old boy with severe intellectual disability, mild dysmorphic features and absent speech, which was associated with terminal loss of the distal arm of chromosome 22. In 1988, Phelan et al.

Cause

• PMS is caused by the deletion or disruption of the segment of the long arm (q) of chromosome 22 that is identified as 22q13. Chromosomes are found in the nucleus of all body cells. They carry the genetic information for the growth and development of each individual. Pairs of human chromosomes include the autosomes, numbered from 1 to 22, and the se...
