Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_004760.3(STK17A):c.798T>A(p.Asn266Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000687 in 1,456,102 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).
STK17A (HGNC:11395): (serine/threonine kinase 17a) This gene is a member of the DAP kinase-related apoptosis-inducing protein kinase family and encodes an autophosphorylated nuclear protein with a protein kinase domain. The protein has apoptosis-inducing activity. [provided by RefSeq, Jul 2008]
COA1 (HGNC:21868): (cytochrome c oxidase assembly factor 1) Involved in mitochondrial cytochrome c oxidase assembly and mitochondrial respiratory chain complex I assembly. Located in cytosol and mitochondrion. Is integral component of mitochondrial inner membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.798T>A (p.N266K) alteration is located in exon 6 (coding exon 6) of the STK17A gene. This alteration results from a T to A substitution at nucleotide position 798, causing the asparagine (N) at amino acid position 266 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
