Ivone Leong (Genomics England Curator)
Initial gene list and info collated by Carl Fratter (Oxford University Hospitals NHS Trust) January 2019 on behalf of the GMS Mitochondrial specialist test group.Created: 4 Feb 2019, 1:36 p.m.
Mode of inheritance
X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
Phenotypes
Linear skin defects with multiple congenital anomalies 1, 309801
Ellen McDonagh (Genomics England Curator)
Comment on mode of inheritance: X-linked dominant in G2P and OMIM. Biallelic mutations in females will be picked up too.Created: 2 Mar 2016, 12:29 p.m.
Comment on list classification: Promoted from red to green due to expert review, and it is a confirmed DD gene for microphthalmia syndromic type 7.Created: 2 Mar 2016, 12:28 p.m.
