Can menkes disease or syndrome show later in life? Can It unnoticed until adulthood? Is this possible? Are you always born with it?

Yes, Yes and Yes. Depending on the nature and degree of aberrant functioning of the gene ATP7A, responsible for copper transport and absorption, one can have classic Menkes disease in childhood, a variant now called Occipital Horn Disease in young adulthood or distal motor neuropathy in mid life. Most of the time the clinical picture does not vary within a family but sometimes it can. For a more detailed discussion of this very compl;ex matter, please schedule a virtual consult. Do consider chromosomal microarray testing and genetic counseling. This gene is X linked so the disease cannot be passed from the father but the gene can be passed to a daughter who will then pass it to her child 50% of the time..
