The fifteen year old is still missing after a week, with her parents finding her room empty and her window open on the morning of Sunday 4th.
She has been described by her parents as 'funny and extremely loving' but also vulnerable as she has holoprosencephaly, a brain defect meaning her verbal communication is limited and cannot write more than a few words.
Her parents described in a statement: "She is unable to do maths and so things like money are impossible to manage."
St Bede's Catholic church in Clapham Park, which she attends, was open nearly every day last week for congregation members to come in and pray. A mass was held on Saturday for her safe return and on Thursday St Bede's will do the same with parish priest Father Marcus Holden
Fr Marcus Holden wrote on Facebook: "Please pray for Nora Quoirin, a fifteen year old parishioner at St Bede's, who is missing in Malaysia on her holiday with family. Please pray for her safety and for her family who are distressed at this time.
"The church at St Bede's will be open throughout the day for prayers for her and at every Mass we are praying for her."
Over 100 people replied that they were praying in the comments.
Nora's Irish mother, Meabh Quoirin, said in a filmed speech to local people in Malaysia loooking for her: "We see you working so hard and also praying with us and being with us.
"You have given up your time especially at a special festival time," she said, referring to Hari Raya Haji, the Islamic 'festival of sacrifice'.
She continued: "To be with us here, it means the world to us. We are so grateful for everything that you are doing for us, everyone who is helping here and not from here.
"We are extremely impressed by the effort, your expertise, your dedication and we hope you find Nora.
"And thank you so much and terima kasih," she said, thanking them.
The Quoirins, an Irish-French family who have lived in London for 20 years, were visiting the Dusun forest eco-resort in southern Negeri Sembilan.
Police have shared this video of Nora Quoirin's mother thanking everyone who is helping to search for her 15-year-old daughter.
