Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 30, 2024The c.86T>C (p.L29S) alteration is located in exon 2 (coding exon 1) of the SMCO3 gene. This alteration results from a T to C substitution at nucleotide position 86, causing the leucine (L) at amino acid position 29 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
