Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.764C>T (p.S255L) alteration is located in exon 9 (coding exon 8) of the STK32A gene. This alteration results from a C to T substitution at nucleotide position 764, causing the serine (S) at amino acid position 255 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
