Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 27, 2022The c.20C>T (p.P7L) alteration is located in exon 2 (coding exon 1) of the SCML4 gene. This alteration results from a C to T substitution at nucleotide position 20, causing the proline (P) at amino acid position 7 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
