Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 11, 2023The c.622A>T (p.S208C) alteration is located in exon 4 (coding exon 4) of the STARD7 gene. This alteration results from a A to T substitution at nucleotide position 622, causing the serine (S) at amino acid position 208 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
