<unk>  (MTM) is a form of centronuclear<unk>  (CNM) associated with<unk> in 1. Genetically inherited traits and conditions are often referred to based upon whether they are located on the "sex chromosomes" (the<unk>  or Y chromosomes) versus whether they are located on "autosomal" chromosomes (chromosomes other than the<unk>  or Y). Thus, genetically inherited conditions are categorized as being sex-linked (e.g.,<unk><unk>  or autosomal. Females have two<unk> -chromosomes, while males only have a single<unk>  chromosome, and a genetic abnormality located on the<unk>  chromosome is much more likely to cause clinical disease in a male (who lacks the possibility of having the normal gene present on any other chromosome) than in a female (who is able to compensate for the one abnormal<unk>  chromosome). The<unk><unk>  form of MTM is the most commonly diagnosed type. Almost all cases of<unk><unk>  MTM occurs in males. Females can be "carriers" for an<unk><unk>  genetic abnormality, but usually they will not be clinically affected themselves. Two exceptions for a female with a<unk><unk>  recessive abnormality to have clinical symptoms: one is a manifesting carrier and the other is<unk> -inactivation. A manifesting carrier usually has no noticeable problems at birth; symptoms show up later in life. In<unk> -inactivation, the female (who would otherwise be a carrier, without any symptoms), actually presents with full-blown<unk><unk>  MTM. Thus, she congenitally presents (is born with) MTM. Thus, although MTM1 mutations most commonly cause problems in boys, these mutations can also cause clinical<unk>  in girls, for the reasons noted above. Girls with<unk>  and a muscle biopsy showing a centronuclear pattern should be tested for MTM1 mutations.
