Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.1195G>A (p.A399T) alteration is located in exon 8 (coding exon 7) of the SCML4 gene. This alteration results from a G to A substitution at nucleotide position 1195, causing the alanine (A) at amino acid position 399 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
