    Is Cutaneous mastocytosis inherited ?
    ### Response:
    Is cutaneous mastocytosis inherited? Most cases of cutaneous mastocytosis are not inherited. They occur spontaneously in families with no history of the condition and are due to somatic changes (mutations) in the KIT gene. Somatic mutations occur after conception and are only present in certain cells.
