Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 28, 2022The c.655G>A (p.E219K) alteration is located in exon 5 (coding exon 4) of the SCML4 gene. This alteration results from a G to A substitution at nucleotide position 655, causing the glutamic acid (E) at amino acid position 219 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
