Genes affected

FRMPD4 (HGNC:29007): (FERM and PDZ domain containing 4) This gene encodes a multi-domain (WW, PDZ, FERM) containing protein. Through its interaction with other proteins (such as PSD-95), it functions as a positive regulator of dendritic spine morphogenesis and density, and is required for the maintenance of excitatory synaptic transmission.

Dec 13, 2023

The c.171G>C (p.Q57H) alteration is located in exon 3 (coding exon 3) of the FRMPD4 gene. This alteration results from a G to C substitution at nucleotide position 171, causing the glutamine (Q) at amino acid position 57 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
