| Retinal disorders v2.241 | PAK2 |
Arina Puzriakova gene: PAK2 was added gene: PAK2 was added to Retinal disorders. Sources: Literature Mode of inheritance for gene: PAK2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: PAK2 were set to 33693784 Phenotypes for gene: PAK2 were set to Knobloch 2 syndrome Review for gene: PAK2 was set to RED Added comment: Antonarakis et al., 2021 (PMID: 33693784) reported two affected siblings from a non-consanguineous New Zealand family. Both had retinal detachment and interstitial parenchymal pulmonary changes on chest X-rays, but only one child had additional significant features such as cataract, posterior encephalocele, severe DD/ID with ASD, and epilepsy. WES revealed a heterozygous PAK2 variant (c.1303 G>A, p.Glu435Lys) in both individuals that apparently occurred de novo indicating parental germ-line mosaicism; however, mosaicism could not be detected by deep sequencing of blood parental DNA. Functional studies showed that the variant, located in the kinase domain, results in a partial loss of the kinase activity. Sources: Literature |
