Genes affected
PLEKHH1 (HGNC:17733): (pleckstrin homology, MyTH4 and FERM domain containing H1) Predicted to be located in cytoskeleton. [provided by Alliance of Genome Resources, Apr 2022]
GPHN (HGNC:15465): (gephyrin) This gene encodes a neuronal assembly protein that anchors inhibitory neurotransmitter receptors to the postsynaptic cytoskeleton via high affinity binding to a receptor subunit domain and tubulin dimers. In nonneuronal tissues, the encoded protein is also required for molybdenum cofactor biosynthesis. Mutations in this gene may be associated with the neurological condition hyperplexia and also lead to molybdenum cofactor deficiency. Numerous alternatively spliced transcript variants encoding different isoforms have been described; however, the full-length nature of all transcript variants is not currently known.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2023The c.548A>G (p.Y183C) alteration is located in exon 7 (coding exon 6) of the PLEKHH1 gene. This alteration results from a A to G substitution at nucleotide position 548, causing the tyrosine (Y) at amino acid position 183 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
