| Mendeliome v1.4261 | MAP2K4 |
Sangavi Sivagnanasundram gene: MAP2K4 was added gene: MAP2K4 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: MAP2K4 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown Publications for gene: MAP2K4 were set to 41480045 Phenotypes for gene: MAP2K4 were set to Neurodevelopmental disorder, MONDO:0700092 Mode of pathogenicity for gene: MAP2K4 was set to Other Review for gene: MAP2K4 was set to GREEN Added comment: PMID 41480045 reports ten individuals from ten unrelated families with heterozygous de novo loss-of-function or missense MAP2K4 variants presenting with a syndromic neurodevelopmental disorder characterized by developmental delay/intellectual disability, epilepsy, and genitourinary and musculoskeletal congenital anomalies. All the reported variants were absent in gnomAD v4.1. DD, ID - present in the majority of the reported individuals CAKUT-like phenotypes reported in 5 individuals Reports of hypotonia in three individuals Epilepsy was reported in 4 individuals A functional study using CRISPR-edited iPSC-derived neurons demonstrates reduced MP2K4 protein and impaired JNK signalling however, more evidence is required to confirm loss of function as the mechanism of disease. There are no pathogenic variants reported in ClinVar in this gene in the germline context. Sources: Literature |
