42240-2 CHD7 gene targeted mutation analysis Find Bld/Tiss Pt Doc Molgen   ACTIVE CHD7 gene targeted mutation analysis in Blood or Tissue by Molecular genetics method   MAJ DefinitionDescription       METHOD: THE ENTIRE KNOWN CODING SEQUENCE OF THE CHD7 GENE (EXON 1 THROUGH 40) AND THE INTRON/EXON BOUNDARIES WERE PCR-AMPLIFIED FROM GENOMIC DNA OF THE SUBMITTED SPECIMEN AND SUBJECTED TO BI-DIRECTIONAL SEQUENCE ANALYSIS. RESULT: Negative NO DISEASE-ASSOCIATED MUTATION WAS IDENTIFIED IN THE CHD7 GENE. A HETEROZYGOUS POSITION (PRO2121PRO CCG/CCA) OF NO KNOWN CLINICAL SIGNIFICANCE WAS OBSERVED. INTERPRETATION: IN ONE STUDY OF 17 PATIENTS WITH CHARGE SYNDROME WHO DID NOT HAVE MICRODELETIONS, 10 INDIVIDUALS WERE IDENTIFIED AS HAVING HETEROZYGOUS MUTATIONS IN THE CHD7 GENE. BASED ON THIS SMALL SAMPLE SIZE, APPROXIMATELY 59% OF INDIVIDUALS WITH CHARGE SYNDROME WITHOUT AN IDENTIFIABLE LARGE DELETION WILL HAVE A MUTATION IN THE CHD7 GENE. THE HETEROZYGOUS CHANGE IN CODON PRO2121 OF THE SUBMITTED SAMPLE IS SILENT AND NOT EXPECTED TO BE ASSOCIATED WITH THE PRODUCTION OF AN Abnormal PROTEIN. THE PRESENCE OF HETEROZYGOSITY IN THIS PATIENT RULES OUT A COMPLETE GENE DELETION AND DEMONSTRATES THAT BOTH CHD7 ALLELES ARE PRESENT AT THIS POSITION OF THE GENE.           MOLPATH.MUT   42240-2   Molgen     Both       0 CHD7 gene Mut Anl Bld/T       N   Blood; chromodomain helicase DNA binding protein 7; Chromodomain helicase DNA binding protein 7 gene; CRG; Document; Finding; Findings; FLJ20357; FLJ20361; Genetics; Heredity; Heritable; HH5; Inherited; IS3; KAL5; KIAA1416; Molecular genetics; Molecular pathology; MOLPATH; MOLPATH.MUTATIONS; Mut; Mut Anl; Mutations; PCR; Point in time; Random; Tissue; Tissue, unspecified; WB; Whole blood; Whole blood or Tissue 2.66 2.16                     Based on LOINC Committee review (June 2016), "targeted" was added to the Component to clarify that this test is looking for a specific set of mutations as described in the LOINC User Guide under the Molecular Genetics section.; Based on LOINC Committee review (June 2019), updated the Property from "Prid" to "Find" and Scale from "Nar" to "Doc" to align with the current LOINC model for naming collections of information reported in narrative and/or structured formats. 0
