Genes affected
ZDHHC15 (HGNC:20342): (zinc finger DHHC-type palmitoyltransferase 15) The protein encoded by this gene belongs to the DHHC palmitoyltransferase family. Mutations in this gene are associated with mental retardatio X-linked type 91 (MRX91). Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.992T>C (p.L331P) alteration is located in exon 11 (coding exon 11) of the ZDHHC15 gene. This alteration results from a T to C substitution at nucleotide position 992, causing the leucine (L) at amino acid position 331 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
