Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2024The c.4T>A (p.S2T) alteration is located in exon 3 (coding exon 1) of the SMIM8 gene. This alteration results from a T to A substitution at nucleotide position 4, causing the serine (S) at amino acid position 2 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
