GeneDx RCV000186755 SCV000240322 uncertain significance not provided 2012-07-05 criteria provided, single submitter clinical testing p.Pro25Ser (CCT>TCT): c.73 C>T in exon 1 of the ALDH7A1 gene (NM_001182.3). The Pro25Ser missense change has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The NHLBI ESP Exome Variant Project has not identified Pro25Ser in approximately 6,000 individuals of European or African American ethnicity, indicating that it is not a common benign variant in these populations. The amino acid substitution is non-conservative, as a non-polar Proline is replaced by a polar Serine, and the loss of a Proline residue may alter the secondary structure of the protein. It alters a position in the transit peptide that is conserved through mammals. However, to our knowledge mutations have not been previously reported in this region of the protein, and multiple in silico algorithms predict Pro25Ser is likely not pathogenic. Therefore, based on the currently available information, it is unclear whether Pro25Ser is a disease-causing mutation or a rare benign variant. The variant is found in EPILEPSY panel(s).
