Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 08, 2024The c.779A>T (p.N260I) alteration is located in exon 6 (coding exon 4) of the LYSMD4 gene. This alteration results from a A to T substitution at nucleotide position 779, causing the asparagine (N) at amino acid position 260 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
