The c.86C>T (p.P29L) alteration is located in exon 1 (coding exon 1) of the TOMM7 gene. This alteration results from a C to T substitution at nucleotide position 86, causing the proline (P) at amino acid position 29 to be replaced by a leucine (L). Based on data from gnomAD, the T allele has an overall frequency of 0.005% (12/251470) total alleles studied. The highest observed frequency was 0.065% (12/18394) of East Asian alleles. This variant has been identified in the homozygous state in individual(s) with features consistent with TOMM7 deficiency syndrome and segregated with disease in at least one family (Garg, 2022; Li, 2024). This amino acid position is highly conserved in available vertebrate species. This alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, this alteration is classified as pathogenic. -
