Genes affected

SHROOM3 (HGNC:30422): (shroom family member 3) This gene encodes a PDZ-domain-containing protein that belongs to a family of Shroom-related proteins. This protein may be involved in regulating cell shape in certain tissues. A similar protein in mice is required for proper neurulation. [provided by RefSeq, Jan 2011]

Feb 26, 2024

The c.401C>A (p.P134H) alteration is located in exon 3 (coding exon 3) of the SHROOM3 gene. This alteration results from a C to A substitution at nucleotide position 401, causing the proline (P) at amino acid position 134 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
