Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2024The c.159C>G (p.I53M) alteration is located in exon 3 (coding exon 2) of the SCML4 gene. This alteration results from a C to G substitution at nucleotide position 159, causing the isoleucine (I) at amino acid position 53 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
