Face Shape Lets AI Spt Rare Disrders
Peple with genetic syndrmes (综合征) smetimes have revealing facial features, but using them t make a quick and cheap diagnsis can be 1 given there are hundreds f pssible cnditins they may have.A new neural (神经系统) netwrk that analyses phtgraphs f faces can help dctrs 2 the pssibilities.
Yarn Gurvich at bitechnlgy firm FDNA in Bstn and his team built a neural netwrk t lk at the verall impressin f faces and 3 a list f the 10 genetic syndrmes a persn is mst likely t have.
They 4 the neural netwrk, called DeepGestalt, n 17，000 images crrectly labeled t match mre than 200 genetic syndrmes.The team then asked AI t 5 ptential genetic disrders frm a further 502 phts f peple with such cnditins.It included the crrect answer amng its list f 10 respnses 91 per cent f the time.
Gurvich and his team als 6 the neural netwrk's ability t distinguish between the different genetic mutatins (变异) that can lead t the same syndrme.They used phtgraphs f peple with Nnan syndrme, which can result frm mutatins in any ne f five genes.DeepGestalt crrectly identified the genetic surce f the physical appearance 64 per cent f the time.It's clearly nt 7 ， but it's still much better than humans are at trying t d this.
As the system makes its assessments, the facial regins that are mst helpful in the determinatin are 8 and made available fr dctrs t view.This helps them t understand the relatinships between genetic makeup and physical appearance.
The fact that the diagnsis is based n a simple phtgraph raises questins abut 9 ．If faces can reveal details abut genetics, then emplyers and insurance prviders culd, in principle， 10 use such techniques t 11 against peple wh have a high prbability f having certain disrders. 12 ，Gurvich says the tl will nly be 13 fr use by clinicians.
This technique culd bring significant 14 fr thse wh have genetic syndrmes.The real value here is that fr sme f these ultrarare diseases, the prcess f diagnsis can be many, many years.This kind f technlgy can help narrw dwn the search space and then be cnfirmed thrugh checking genetic markers.Fr sme diseases, it will cut dwn the time t diagnsis dramatically.Fr thers, it culd perhaps add means f finding ther peple with the disease and, 15 ， help find new treatments r cures.
