Upon examination he is morbidly obese, short stature, pedal edema, facial puffiness, polydactyly of feet, micro penis and retinitis pigmentosa. He presented with primary pentad features of LMBBS with CKD stage 5 for which he was started on hemodialysis. He also had secondary features of speech delay, developmental delay, dental crowding, high arched palate and ventricular hypertrophy. Management of LMBBS is supportive. genetic counselling of affected families raises awareness about need to get the other family members assessed for renal and cardiovascular problems.
