Genes affected
SPOUT1 (HGNC:26933): (SPOUT domain containing methyltransferase 1) Enables miRNA binding activity. Involved in maintenance of centrosome location and production of miRNAs involved in gene silencing by miRNA. Located in kinetochore; mitotic spindle; and spindle pole centrosome. [provided by Alliance of Genome Resources, Apr 2022]
ENDOG (HGNC:3346): (endonuclease G) The protein encoded by this gene is a nuclear encoded endonuclease that is localized in the mitochondrion. The encoded protein is widely distributed among animals and cleaves DNA at GC tracts. This protein is capable of generating the RNA primers required by DNA polymerase gamma to initiate replication of mitochondrial DNA. [provided by RefSeq, Jul 2008]

The c.1070T>C (p.I357T) alteration is located in exon 12 (coding exon 12) of the SPOUT1 gene. This alteration results from a T to C substitution at nucleotide position 1070, causing the isoleucine (I) at amino acid position 357 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
