here's a list of all the autosomal recessive diseases that you really need to know for USMLE and comlex note that this is not an all-inclusive list and there are definitely some diseases that I've intentionally left out the reason that these are the diseases that you need to focus on are because these are the highest yield ones that get tested and they ask you something along the lines of the first-order question such as how is this disease inherited or in what fashion is this disease inherited so I recommend starting with this and if you get familiar and comfortable with this song then you can add on whatever else you need to know on top of it but just as it always goes with my videos it will only take you about two minutes to get this down and you'll never get a point wrong if they ask you how autosomal receives it's autosomal recessive is actually inherited so you've got alpha 1-antitrypsin deficiency beta thalassemia phenylketonuria or PKU hemochromatosis Wilson's disease Bernard Soulier heart nut syndrome clansmen throb asthenia and Fanconi anemia so now I'm gonna sing you this song and you see the lyrics right here and after I grew through this song I'll say exactly what diseases that each word refers to but it should be pretty easy so it's to the tune of happy birthday so here's the song alpha beta pu iron copper burn su hearten of glands min Fanconi AR yes it's true so pause the video and rewind and listen to me singing that back to you a few times you can memorize it but it's pretty straightforward so let's go through the diseases and which word represents which disease so you won't forget these alpha represents alpha 1-antitrypsin deficiency beta represents beta thalassemia pu represents PKU because recall that and that disease patients have what's classically described as a musty odor so pu they smell bad iron is hemochromatosis it's iron overload likewise copper represents Wilson's disease burn sue is Bernard Soulier heart enough is obviously heart enough clansmen is obviously Klansmen and Coney is obviously Fanconi anemia and then at the very end of the song AR that stands for autosomal recessive so I always end the song with something that reminds you whether what we're talking about so if it's AR it's autosomal recessive and of course I have the other songs about x-linked recessive autosomal dominant and reportable diseases but one more time from the top alpha beta pu iron copper burns su Hartnell Klansman Fanconi a r yes it's true good luck guys
