TLDR Researchers found a new genetic mutation linked to a hair condition in a Japanese boy.
In 2016, researchers discovered a new splice site mutation in the LIPH gene of a 4-year-old Japanese boy with autosomal recessive woolly hair (ARWH). Alongside a known missense mutation (c.736T>A) in exon 6, the boy also had a novel heterozygous mutation (c.417+1G>C) in intron 2. RT-PCR analysis showed that this new mutation led to abnormal splicing and a 144-bp deletion in exon 2, which likely results in the loss of an important N-terminal α-helix in the PA-PLA1α protein. This finding adds to the variety of LIPH mutations associated with ARWH.
