Claims

  • Breed: Pixiebob Longhair (Cat)
  • Disorder: Feline familial HCM
  • Mode of inheritance: Autosomal recessive
  • Summary: Information listed here was previously listed under 'a href=../../../../../../OMIA000515/9685/OMIA:000515-9685/a : Cardiomyopathy, hypertrophic', an entry that now describes generic information about HCM. See also 'a href=../../../../../../OMIA002951/9685/OMIA:002951-9685/a : Cardiomyopathy, hypertrophic, MYBPC3-related, autosomal dominant' [30/04/2025].nbsp;brThe original entry was edited by Meg Sleeper, VMD and Vicki N. Meyers-Wallen, VMD, PhD, Dipl. ACT and has been updated.
  • Defect: yes

Associated gene(s)

Derived from OMIA database dump (omia.xml, local); structured field, not verbatim prose. First-hand values below are verbatim substrings of the topic's pdf-raw/omia/<phene_id>.txt source file.

  • Gene: Entrez Gene ID 398299006 (no symbol in OMIA GeneSynonym) — OMIA Phene_Gene
  • OMIA molecular-genetics note: HCM is genetically heterogeneous in the overall cat population. By sequencing a very likely comparative candidate gene (based on the homologous human disorder), Meurs et al. (2005) identified the causative mutation in Maine Coon cats as a G to C substitution in exon 3, codon 31 of MYBPC3 (omia.variant:901). This changes a conserved amino acid (alanine to proline; A31P), which most likely changes p…
